Social network graph of #slaname tweet replies October 14, 2009 to December 11, 2009.
The thicker the line the more times you sent an @reply to that person. The more lines you have, the more @replies to different people you sent. If you don't appear on the graph, but know that you sent out @replies, it's because the person you sent your @reply to never sent out an @reply and so that person won't appear on the graph and unfortunately, you can't either!
