As someone who once played around quite a bit with Community Server, I still follow the CS developer community quite closely. A while back there was quite a bit of buzz in the CS community (and the blogs in general) surrounding Telligent's release of BlogMailr, a free email-to-blog service.
I know I'm a little late, but since I just got around to implementing the MetaBlog API, I'm just now able to test it out with my blog. Don't know if I'm so addicted to blogging that I need to be able to write by email, but it's nice to know that i CAN.
