I just put out a tweet to see how they did it for @Podcamp
I know that one thing that could be done is simply to do search on Summize for any messages sent TO:PodcampOHIO
Here is the current result:
http://summize.com/search?q=&ands=&phrase=&ors=¬s=&tag=&lang=all&from=&to=podcampohio&ref=&near=&within=15&units=mi&since=&until=&rpp=15
Then you can grab the rss feed for that search here:
http://summize.com/search.atom?q=+to%3ApodcampohioThen you could use TwitterFeed.com and have twitter feed check the above rss every 15 minutes and auto post the most recent 5 updates to the podcamp ohio feed OR another account if you like.
Or you could just tell people to put a shortcut on their phones to the summize search query from above.
The cool thing about the auto posting is that I would get SMS each time someone posted to the acct. But I'm cool with whatever.
Hope this is helpful.. If I get anything back from the Podcamp Boston folks on a more efficient setup, I'll let you know.
