I tried out one of those services that analyzes your Twitter feed and tells you things like who "influences" you, who you influence, and so on. I think the algorithm might need a little more work:

"Pirates" made at least some sense to me. "Parenting" was a much bigger surprise, but after running a search I guess I have offered a few suggestions on that from time to time.

How "influential" I have really been on either group, though, is probably extremely debatable.

Parents, pirates, or others who think they might like to be influenced by this (140 characters at a time) can follow the Twitter feed at @loweringthebar.
