I'm another Radio refugee. I saw a reference to Scott's site on Sam Gentile's Blog, via Peter Drayton’s Weblog which I got from... the usual surfing about. I'm professionally interested in .NET and personally interested in the blogosphere so this is a great place to be - Thanks Scott for letting me join.
Between Radio and here I've been using Moveable Type for my personal site. MT is pretty solid blogware and I like what they've done, but I'm not a PERL-head, so MT extensibility seems too much like work to me, as opposed to .NET extensibility, which seems much more like fun. The integration with Syndirella is an exciting idea, and really seems like the right direction, I'm looking forward to being part of the ASPNetWebLog (that's a mouthful) community.
