I haven't participated in it, though I've thought about it. It is extremely accurate though, perhaps more accurate than the polling. In the 2008 Presidential election they got all the states right except for Indiana and Missouri, and those two states were decided by about 1,000 votes.
538 has Rand slightly better than that! I disagree with Nate Silver politically...but he's ridiculously accurate when assessing a large number of polls. This is a great sign.
