Mashable posted about Lunch.com's new ability to organize and post Twitter lists (http://mashable.com/2009/09/30/lunch-twitter-lists/). In it they mention TweepML.org for a comparison. I checked out both and there's two different purposes.The Lunch.com lists are imported from your followers. You can organize your followers into lists and people can easily follow your "groups". It would be like Tweetdeck allowing you to publish your "groups" as "who to follow" lists. TweepML.org makes it easy to publish groups that may not be in your following. For me, it allowed me to quickly publish the attendees of WBC 09 and the members of OWC – over 1000 wine people in total. Other people have published wineries, etc. Its really jolted the wine community into another gear on Twitter. You can't do the same with Lunch.com. Lunch.com is cool, but not really a tool for stoking a community. Just a way to introduce your friends to other people really. Anyway, just FYI. I poked at it for a little bit today and that's what I found. Cheers!
