An interesting thought occurred to me while reading about the tepid sales of SYNSO! on XBL Indie Games. (See http://www.xnplay.co.uk/2009/11/19/squid-yes-not-so-octopus-sales)

XBL should provide a Twitter-like stream of updates from your friends, which would include things like “FriendX bought SYNSO! and rated it 5 stars! (X) to see SYNSO!” There could tremendous viral/auto-word-of-mouth effects with such a system and really let great games bubble to the top… or at least make you aware of their existence.

Well, anyway, $1 well spent on SYNSO!, I suggest you purchase it too if you haven’t — http://marketplace.xbox.com/en-US/games/media/66acd000-77fe-1000-9115-d8025855035b/
