I've noticed a few people saying they have only seen this the past few days (as have I). However, on the unfiction forums, there were post made in APRIL about this (google cache to the rescue).

The more I see, the more this looks like an alternate reality game in the making. We'll all find out soon enough though. Eon2 though, no links? Confersketch all link back to the eon2 page. IMO, related pages.
