BLOG is a free and easy way to get timely information onto the Internet. It is a combination of software tools and web hosting that allows anyone to keep and maintain an online journal without having to learn complicated computer or Web design skills. It’s a personal publishing system that gets your thoughts into cyberspace instantly. There’s no way to count the number of blogs, but estimates start at a million and go up from there. Seeing a blog is more enlightening than reading about them, so have a look at my newest blog.  In fact, you can finish reading this column there. The first thing that you will notice is that it is arranged chronologically, with the newest entry on top. This diary format is the defining characteristic of blogs. They are intended for instant and frequent communications. I found that the service called Blogger, owned by Google, is the easiest to use, especially for beginners. Another good free service is Journal Space. With all of the blog services the first thing to do is to set up a free account, which essentially means giving the service your name and e-mail, selecting a password and a name for your first blog. The blog name will become part of the address -  yourblogname.blogspot.com. In Blogger, you can have unlimited blogs. Journalspace gives you one, and your user name becomes you blog address, so pick it carefully. So you don’t get confused, Blogger is the name of the service and the address you visit to manage your blog. Blogspot is where the blog is actually hosted, and the address that your visitors use. They are the same service. The other required action is to pick a blog template, or the look and feel of your blog. The service will give you a set of templates from which you may chose (and easily change if you change your mind.) More experienced users can download other templates from third-party sites, design their own templates or modify the ones provided (they are created in HTML and Javascript: you have access to the code.) That done, start blogging! Each entry is called a post. You type in your post, then publish it (click a button) to make it go live onto the Internet. If you want, add a few hyperlinks and format the text, just as you would with a word processor. There’s even a spell checker (hint, hint.) That’s it. You can master the basics of blogging in about five minutes. But why stop with the basics? Most blog hosts allow you to post pictures onto your blog. Blogger doesn’t have an innate photo capability so you have to use a third-party program or service to transfer photos to your blog. Hello, from Picasa Software, is a free program that is installed on your computer. Hello is sort of an instant messenger optimized to facilitate sharing photos with friends, but an added feature is a “bloggerbot” (bot is shorthand for robot) that sends pictures to your blog. It’s quite simple to use. Master this in about a half hour. Another way to add photos to your blog is through another blog (are you confused yet?) BuzzNet is a photoblog, sometimes called a Moblog. The MO stands for mobile: many people use these to share photos taken on their mobile phones. You can send photos by e-mail over the wireless access protocol, or WAP, as well as using BuzzNet’s easy Web-based interface. After you set up your free account with BuzzNet you can upload up to 60 photos per month. If that’s not enough, you can buy more photo storage (100 more images in a month for $5; $15 for 300 images, or go for it and get their premium service – no banner ads, custom templates, password protected galleries and 250 photos a month – for $36 a year.) BuzzNet is optimized for photos rather than text; it’s set up more like a gallery, although there are ways to add comments to photos. One of the options is “Blog This!” which will send a photo and text to your Blogspot blog with the click of a button. BuzzNet is especially handy if you are traveling and are using someone else’s computer – at a cyber café, for example. Since the interface is Web-based, you don’t have to worry about installing any software. Hint: if you do a photo blog while traveling with a digital camera, get a USB-based card reader (something like the SanDisk 12-in-1 Memory Card Reader, about $35) so that you can read your memory card directly into the alien computer. If you are in the US and taking photos with your digital camera this is not necessary. I set up a BuzzNet account: you can see my moblog there. If photos aren’t enough, how about audio? Both Blogger and Journal Space allow audio blogs, which are sound files that you call in from any telephone and are automatically posted to your blog. These work through 3rd parties and are considered “add-ins” to the blog. You can listen to one. I used a service called audioblogger which is free and lets you post an unlimited number of 5-minute long messages by calling them in over your phone. Some other audioblog services allow much longer posts – up to an hour! – and allow you to record them on your computer using a microphone. Some people are actually doing full-length “radio” shows using audioblogs. Sometimes this is referred to as “PodCasting,” as people download the audio from the blog onto their MP3 players (an iPod, for example) so that they can listen to it away from their computer. Video blogs (Vblogs) are also starting to show up. Look at audioblog.com for more info: their service is $50 a year. This really just skims the surface of blogging. You can set up team or group blogs that multiple people can post to. You can enable a feature that allows others to add comments to your blog. There are blog communities that interact with each other. Most blogs, including Blogger, will automatically set up an RSS (syndication) feed for you. If you have your own Web space, Blogger allows you to integrate it with your web content so that it uses your URL. Blogging can be serious business. Last summer, Express-News military reporter Sig Christenson maintained a daily blog from the battlefield in Iraq. They can also be silly and superficial. What you blog is up to you. For personal use, a blog can be used for vacation photos – while the vacation is still happening! They can be used for family photos – a wedding? New baby? Or even just to post your musings. If you have the Google toolbar installed, there is a Blog button on it. If you click it, it will automatically post a link to the page you are currently viewing to your BlogSpot blog. Many people use this feature to share interesting sites with friends. But blogs can be used for business, too. They are an excellent way to get current news up onto the Web fast; even someone with no technical skills can do it without waiting for the office Web guru to fit you into her busy schedule. Here’s a warning. Any free service, blogs included, can go out of business. Weblogs, a free service started by blog pioneer Dave Winer, suddenly shut down last summer, leaving thousands of bloggers homeless. Give it a look. A blog might be all you need, or it could be a trendy and useful add-on to a full-blown Web site.
