Excellent Open Source Blog Software
I came across DotText or .Text and decided to try it out on my local IIS at work. I'm using it to help me keep track of the various projects I'm working on. At the end of the day I make an entry to tell myself where I'm at and where various files are that I'm working on. I also make entries when I come across things I want to make a note of for the future (like that Visual Studio "repair" problem a few posts ago). The posts are stored in my local SQL Server so I can do queries against it to easily find stuff.
So far it is working very well. You can download source code or binaries from GotDotNet - .Text Home. (Warning: the server is sometimes slow, so be patient.)
