Cory Doctorrow writes on boingboing:

As with last year, Slashdot's RSS server has banned the entire O'Reilly Emerging Technology conference from pulling its RSS feeds. There are about 400 geeks here running RSS readers that are pulling Slashdot's feed from behind the same IP address, as Slashdot's systems have interpreted this as one user repeatedly reloading it.

Why didn't any of those 400 geeks at the Emerging Tech conference emerge some tech (e.g. a local cache) in the past year to prevent this problem?
