Except that Digg sends this kind of traffic within a shorter period than
one day ;-) Sometimes it can bring a webserver to a halt if only 100
users decide to visit your blog at the exact same time. But if one wants
to prepare for digg/slashdot, nothing beats a proper cache that serves
more or less static pages.

That may be the reason a switch to innodb isn't doing that much
performance-wise. Accelerators help a lot and having wordpress not
format every post on each view (http://vapourtrails.ca/wp-preformatted)
helps too. But - as seen - caching beats everything, even a badly
configured server ;-)

+1, but I cannot get rid of all these little things ... so cute, and
helpful, slow ... damn it :-)
