Thirdkind did, for his website (he's still in version 1.x). I would link to his site, but I don't think the mods would appreciate the content >>
I've been using 2.0 since they released the official version. If you stopped by once in a while, you'd know that

And as far as content goes, stop by the main page and see the big blank white space. That's what happens when the webmaster takes a breather for the holidays and the date stamps on the news posts causes them to be archived
As far as features are concerned, FuseTalk is a great package. It's also very stable, being based on CF and databases, as opposed to CGI and text files like UBB. Of course, since you need to have a hosting service that supports ColdFusion (or host it yourself with CF Server), the cost is higher. Also, if you plan on making any changes to the code itself, such as adding features or tweaking the layout, you'll need to shell out ~$300 for the source code version. The standard version is encrypted and non-hackable. As you can tell by using it, however, in its short time on the market, FuseTalk is a more feature-rich and better developed product than the UBB.
If you're looking for a ColdFusion hosting service, I recommend
Media3. Very fast, and their prices aren't too shabby.
