This is pretty nifty. Twitter approved us for "summaries" - here's how they look:
If you would like your byline to be displayed (as John's is in this example), be sure to edit your profile here and include your Twitter handle (without a "@") in the appropriate box. Twitter will grab your "name" from that account - or leave it blank if there isn't one.
If you use the optional "Summary" field when you start a new thread, that will be used as the text of the Twitter summary as well. (If you don't, we'll grab the first sentence or two of your post and make THAT the summary.)
I *believe* any tweeted link to our domain will generate a summary, but I suppose we'll find out for sure as we go.
