Scaling WebSites: 10 Presentations

Peter van Dijck (of mefeedia fame) has put together an incredible collection of slideshows on how to build websites that scale.
Slideshows from flickr, livejournal, twitter, six apart/vox, and last.fm are included. The fascinating thing is how similar the presentations are. We all owe a huge debt to livejournal/danga for giving us free, open-source, powerful tools like memcached and mogilefs and perlbal.
