GT has built a custom app for me that serves as a blog for my organization using the GForum plumbing. It essentially pulls root posts in specified forums and formats them using GF templates and is posted as static pages to a different website (
http://www.pecupdate.org). They also built a subscription service using templates under GList. While not a true blog per se, but exactly what I wanted/needed to repalce an old newsletter site. The discussion forum (RxNET) restricted, so sorry,no general access. If any of you are interested, I could post some screenshots of the interface, a modifed version of the post template.
We are just ramping up the site, but it looks great
!
I believe it was all built as two plugins (GF for web, GL for subscription functions) and templates....so GT may be willing to sell it to others.
