@Ryan - Yeah, the dev blog is good but, seriously, even of the minority of people who use RSS (everyone should IMHO, but they aren't), how many of use are truly on top of our feeds enough to trust it as a way to receive urgent notifications?

The same goes for Twitter.

For all its faults, email remains the surest way to get information in front of people quickly and, again, the dev blog RSS feed can't remind you how many blogs you have out there and what version each of them is.
