The reason CUUSOO is still in Beta is because they haven't yet found the perfect format for LEGO CUUSOO. They are still trying to fix various things, though they have managed to find solutions for a few problems. If you look at the history of LEGO CUUSOO, you will see a lot of changes in how things are run:
 * LEGO CUUSOO started out Japan-only; changed to be available worldwide
 * When it opened to the entire world, the critical number changed from 1k to 10k
 * As more projects began reaching 10k, the CUUSOO people realized that Reviewing each one individually would require too much work, so they formed the Quarterly Review
 * Sometimes people went overboard "Nah"ing comments that they didn't like, and CUUSOO thought it might hurt people and cause them to leave. Thus the "Nah" button departed.
 * Comment sections became popular, and there was a lot of SPAM. In order to correct this problem, they began deleting "off-topic" comments, which did end the SPAM but also hurt the community. Fortunately, this place got up and running at the right time.
 * The 26th Achieved project just passed. It's a Ghostbusters project. It looks like another one is also coming up (at 8,100 supporters). If it makes it into this Review period (unlikely) will they once again change something?

There's still a lot to work on, which is why CUUSOO isn't out of Beta.
