Before taking leaps you need to learn to walk, beginning with fixing bugs, get rid of hustlers vendors in store and make a real native android/ios app rather the site incapsuled. Once u be there u can take a a small jump in comparison to Facebook. As a developer seeing those bugs through out the years i am with you, i am supprise you are still exist. 

Didn't mean to thank this post, wanted to comment instead -
While there are some weird old bugs, I do love the leaps that UNA makes in some of the major releases, so I think its nice to have a healthy balance of both. Me and others love their work regardless of the bugs, so I'm not surprised they exist.
