It's hard to say what exactly is happening right now, but I don't think there's much of a reason to expect an industry wide "pop" soon. As mkr-hn said, the companies are certainly more responsible now than a decade ago, and despite the seemingly outrageous valuations of companies like Facebook, Twitter, and Zynga, there are equally as many reasonable valuations for smaller, still successful, tech companies.
