I have just setup mu pingpressfm wordpress plugin to add a couple of hashtags so that I come up in twitter hashtag searches :) I added #musicblog and #macblog. I have a lot of posts waiting on my mac at home to fill up the music part, and I have realised that I have a lot of posts to re-write. at least I have an iphone now so I can write on the train :)
if you use tweetdeck then setup an automatic search for #haiti :)
