I've used Drupal 7 for the last five or six years and would never recommend anyone use it for anything whatsoever.
I've used Drupal 8 in passing and it's basically a relatively modern PHP framework that is encumbered by some of the ideas from the earlier versions of Drupal. I'm not an expert but I wouldn't recommend anyone use it when there are better solutions out there that cover the same ground.
The community is quite nice though, and there are some especially helpful people on freenode/#drupal_support.
