Super Cache Makes Your WordPress Blog Super Fly
Donncha O'Caoimh is the man behind WPMU on which blognation runs and is one of the lead developers in Automattic. He has just released WP Super Cache which enables WordPress and WordPress MU sites to deal with large traffic loads and avoid the dreaded Slashdot Digg effect.
It sounds like a serious improvement over WP-Cache which I have tried and discarded several times due to it not playing nice with other plug-ins.
He'd also like everyone to Digg it, so he can show how his server isn't even breaking a sweat when running the new code!
