I got the same email this morning.
There's a surprisingly substantial amount of the content that "is" available elsewhere (not a shock - one could attend a SQL Saturday and attend enough sessions to get the equivalent of what you'd otherwise have to shell out a box of ziti for at a conference )
But $49 dollars to save a TON of blog-spelunking is a great deal.
T-5 hours before my big road trip - wish I could meet up with you, but I have a really tight travel schedule. (I am going to try to get out to KC for an entire weekend this fall to see a Chiefs fan)
