I have joined Twitter, username @BobbyJayOnFood. I have only been on it for about 10 days, and am so far keeping a pretty low profile, following mainly food writers. Even so, I have found some interesting people following the same writers, and have already discovered some new bloggers to follow and at least one good recipe. In addition to my blog posts, I expect to share quick thoughts on (primarily but not only) food and provide links to content that I think others will find interesting.
Not many people are following me yet, but hopefully that will come in time.
I have also placed Twitter (and other) buttons under my posts so that others can tweet them to their own Twitter feeds if they are so inclined.
