We had a lot of ideas / pivots that were released or almost released and never made it: leaving video messages for your friends on Facebook (when the first platform came out in '07), a live streaming API, a gaming site for live video streams (yes, we actually pivoted to TwitchTV twice), CamTweet (a way for you to share live video on Twitter), and more that I probably can't remember.
As Tim noted, props are due to the JTV team, who stuck around and kept building things where reasons to continue were scant, which was often.
