It might not be the next bubble (rather next decade's bubble), and not as big as the mortgage securities bubble, but I have my eye on siloed social media in general and Facebook in particular. I don't know exactly how or when the federated/web-of-trust alternative to Facebook will unfold, but people are definitely working on commoditizing this stuff, and doing so in an unassuming way that has the potential to catch major players by surprise when it finally crystallizes. I'm not convinced that any of XMPP, GNU Social/OStatus, diaspora*, or IRCv3 have all the pieces to solve the puzzle, but the direction they're pulling is not a big mystery, and I consider it a very real possibility that a successor to those efforts does to Facebook what HTML5 did to Flash.
