I've recently gotten interested in blogs and now subscribe to a number of education blogs. Just a few weeks ago I started my blogging class and have even started one!
Wikepedia defines a blog as follows:
"A blog (a contraction of the term weblog) is a website, usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. "Blog" can also be used as a verb, meaning to maintain or add content to a blog.
Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blogs, Web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs."
Here's a great video that helps you understand blogs. Common Craft has wonderful videos that explain technology in simple terms. I like simple!! If everything works right, you should have a video to watch. I have my fingers crossed!
