It's only about 6 months old. My only experience was getting it up and running locally and testing out the functionality. It took a couple of hours to get going (mostly due to updating gem versions). From my standpoint I was happy with how it looked. I had considered Wordpress and Drupal, but I liked the smaller, more manageable codebase - even if it meant I may be fixing bugs in the project code as I went.
I hadn't checked in on the project in awhile. I'm surprised it's not more active. FYI it looks like there was a fork recently and Luvfoo is being more actively developed (but no existing community)
