But now MySpace has bought iLike and things are going to change. Facebook is going to kick iLike widgets off their site because that it's owned by it's top competitor MySpace.
Fortunately, for now at least, there's no need for alarm. MySpace has very publically stated that its not going to change iLike – just use its know-how and technology. And Facebook is very unlikely to enradge millions of users by kicking its #1 music app off its supposedly "open" site; at least until it develops a music strataegy of its own.
Things certainly can change and Hypebot will be watching it all closely for you. (In fact, if you see anything weird email me at hypebot(at)skylineineonline(dot)com and I'll investigate) But until then, rest easy, I've got your back.
UPDATE: CNet reports that iLike will soon debut downloads on Facebook app.
