Stone is a cool idea. I like the no database idea. I remember being at RailsConf 2007 and hearing Avi Bryant talk about SmallTalk and his database less SmallTalk web framework called seaside, <a href="http://www.seaside.st/" rel="nofollow">http://www.seaside.st/</a>.<p>Later Dave Thomas gave his keynote and asked a similar question of are relational databases the way to go? Why aren't we trying out OO DBs? It would be nice to see some benchmarks on Stone, anyone know what speed for it is like?
