I was asked about my weblog engine in email and in comments, so I'll just post a quick reply.

Its pretty much a very simple home-grown blogging engine along with a web-based admin front-end thats still partially in the works. All built on ASP.NET v1.1... of course. All the data (entries, comments, links etc.) is managed in a SQL database. The pages were developed in
Web Matrix (as part of app-building exercise while preparing for a new updated version - more on that specifically in a future post sometime soon).
