My earlier review in the Hubitat thread:
>software
It suffers from ajax overload, glitzy features, and mediocre nav ui, but the content is worth the pain.
Add poor advanced search parameters to the above. Can't figure a way to add a negative search parameter.
That aside, the software grows on you --particularly some UI features while creating a post.
Besides Hubitat, I believe Samsung is also using Discourse for Smarthings. If I were looking for a commercial or enterprise forum, it would be a contender.
