Ivan, the Belgian .NET developer and member of the Wellington.NET user group just moved his blog from DasBlog to Subtext.
He is a very smart guy, with lot of interesting opinions about development, not only .NET but also Ruby and other "cool" languages, so if are not already subscribed to his blog I encourage you to do so.
He also decided to stop developing nBlogr, his own blogging engine: it's always sad when someone decides to stop developing his own project for lack of time.
Hopefully Ivan will contribute to Subtext, and with the plugin framework we are adding to Poseidon, he will be able to do it without mastering the core of the engine, but only implementing an interface and subscribing to some events.
