I just came back home from a very intersting meeting of the Wellington user group:
Ivan Porto Carrero (as you can guess by the name, he is not a kiwi, but comes from the land of beer, Belgium) spoke about his blogging engine: nBlogr
It's a blogging engine built using castle, base4.net and prototype. It's still in an early alpha phase but given the simplicity and the extensibility of the code and architecture I saw at the presentations, I think it can become a good .NET blogging engine in the future, if Ivan goes one builiding and maintaing it.
If you want to know more, read the post he made about tonight presentation, with link to the powerpoint presentation, and a brief step-by-step guide on how have nblogr running on your computer.
He is also looking for help, so, if you want to experiment with all that alternative non standard way of builing web app with the .NET framework, if you want to learn boo, and if you want to work with a smart guy, please contact him: I'd really love to contribute, but I'm already doing soo many things after work (Subtext, watching the Americas Cup,CC.NET Monitor, studying for the MCPD, working on a WLW plugin, rockclimbing indoor) that I don't have time to work on it.
Sorry about that Ivan.
