Check out the preview video:
Next week - Tweet and Taste Michigan. Monday, June 7 at 7 pm CST....Get onto Twitter and search #ttmi. If you have any comments make sure to toss #ttmi in there as well.
I haven't tried this in real time, but messing around with TweetChat has been quite enjoyable. I'm going to try it out - basically you just punch in the hashtag you want to follow (remember: #ttmi) and it refreshes automatically all posts AND adds the tag to all of your posts (one of my biggest problems was forgetting the tag).
Should be a good time - check it out on June 7th!
