Yesterday Paul Buchheit (Y Combinator, FriendFeed co-Founder and GMail creator) posted 'Open Spark Project - Your Music! Played through Lightning!' on FriendFeed. Pretty cool. I can only imagine how the music and entertainment industry will use this invention in the near future!
This also reminds me that the Like was originally a FriendFeed concept that was later adopted by Facebook when they acquired FF. As FriendFeed is my all time favorite social network, this Like from FriendFeed co-Founder made my day!
