I've started a Twitter feed (on the right). It seems like a good, low-expectation, easy way to post updates on the garden. The formatting is a bit ugly and hard to read, but if you tweet, you can always subscribe directly to my Twitter feed... I already appreciate the ability to quickly check when/what was planted, when things sprout, etc. Sometimes that information seems too unimportant to post on the blog, but just right for a quick tweet.
