I use ScrewTurn wiki for a few different things. It’s an excellent free WIKI.
I setup one up for NOODB, and have started populating it. My plan is to put all relevant information there, and refer to it in blog posts. You can also subscribe to RSS feeds on the WIKI directly.
The code formatting on ScrewTurn isn’t good; the attributes are showing up as links, and it otherwise doesn’t look C#ish. Until that is resolved (which is not a high priority), I’ll continue to post the code samples on HamletCode.
