I consider Kathy Sierra (and her husband Bert Bates) good friends of mine. I've seen them quite a few times over the years at various conferences. They're some of the nicest people I've ever met and I always enjoy our conversations.
The recent death threats she's received is sick and wrong. I don't know what to say, except that I hope they find the morons that are doing this and prosecute them appropriately.
I like Scoble's idea and will be taking the week off as well. Too bad, it looks like there won't be an April Fools entry this year.
