Should I Blog?

I don't really like keeping a journal but I need a way to communicate what I am thinking about the use of technology in Mathematics. I like using the Internet and have at least ten websites. This is a problem since I need to keep them all updated. One issue is having an rss feed or way to interact with folks on a website. Maybe a google group? The other possibility is the Ning site. I need to pursue how this might work over the next month.
