Hi Paladin! I (site owner) share basically all of your concerns. :)
One of the big goals going forward is not just more gender equity, but a wider range of body types, ethnicity, and age. Also we are trying hard to discourage "sexy" or "glamorous" poses and preference more everyday or classical art poses. This is a little hard, as the majority of photographers who have contributed photos seem overwhelmingly interested in photographing young, white, skinny, female models.
The fundraiser unfortunately did not reach the threshold that would have allowed us to schedule our own photoshoots immediately. However, we've been working on alternate ways of sourcing more photos in the meanwhile.
Time tracking and achievement features are not just planned, but already built - they will be available after the site relaunch happening in September, along with a plethora of other improvements.
There are a TON of posts up about what we're planning and how the execution of that is coming in the site news section, including stuff that addresses all of your questions, so I would suggest browsing through those if you're interested in knowing more.
