My ol’ chum Jamie has found an interesting site. There’s lots of detail about various design patterns and where to use them, but the design of the site itself could do with a bit of improvement. Still, well worth a read.
This is taken straight from the patternshare home page, they say it better than I can:
PatternShare.org is a wiki site that aims to increase pattern sharing, dialog, and usage by bringing together people who want to learn proven solutions to common problems from people who have solved them before. The pattern format combined with the flexibility and community ownership of the wiki make the site ideal for this kind of community.
