Finally, my blog has moved to ThinkJot V2. This is still not a production ready release, several key features are missing. But things are good enough to run www.process64.com on V2. This is a total rewrite of the code base. The code is licensed under the Apache 2.0 license.
Update: I received a lot of queries about when V2 will be released. The answer is sometime next month. There is a lot of testing, and security code reviews to be done, in addition to important missing features like trackbacks, monitoring activities, performance tweaks, getting it to work on Mono (there is a Mono MapPath issue). So the source code is available only from Google Code using SVN. URL: http://thinkjot.googlecode.com/svn/trunk/
Update2: You can download the TJ-V2-Alpha-Source as a zip
Update3: Using the new multi-blog feature, the Thinkjot homepage now runs on V2 too.
Most prominent new features are
1. Multiple Blog support
2. Neat, no-frills source code
3. More capable templating
4. New Provider based design for fetching data (plugging in Sql is easy, working on it)
5. Full Open Source (TinyMCE, instead of FreeTextBox)
6. XHTML!
7. Medium Trust without hacks
8. Save as Drafts
9. Undelete Posts
10. Limited file management
11. dasBlog 1.8/TJ v1.0 migration utility
