Earlier today I linked to R. "Ray" Wang's post on the lack of innovation on the part of enterprise software vendors. One of the key trends Wang mentioned, and we've mentioned here as well, is the "consumerization" of IT. According to Wang, vendors are borrowing extensively from consumer technologies like Facebook for ideas. And most of the technologies we think of as "enterprise 2.0" have been around as enterprise products for some time now. So I'm curious: how many of you are actively using this stuff in your organizations today?
