A blog is basically an online diary. I have one at: http://miltmussings.wordpress.com/ which I plan
to update occasionally to add new information about tools and technology.
Most blogs have tools that make it easy to keep content current and to link to people. Many of
them have RSS feeds and other notification capabilities. But a word of caution - a blog can get
stale fairly quickly, I know I have a few stale blogs lingering on the web. So plan at least an hour a
week of care and feeding.
Wordpress www.wordpress.com has become a very popular blogging tools. There are many more
and the tool isn't that important - Its the content that matters.
