Tearing an already small community is pretty counterintuitive to trying to help it and grow it. Personally, I intend to continue to develop Glass. You've done a nice revival here, it looks pretty clean. I'll do what I can to avoid conflict, allowing the services to work side-by-side, and I hope you'll do the same.
The reason I decided to take a from-scratch approach is to rebuild the system from the ground up. I too have been coding as a profession. While RTB was great, it did have some flaws and features that just couldn't be addressed because of the way it was structured from the ground up. On top of that, Glass is intended to be headless so that it can continue if I suddenly want to leave it behind. It's developed with some newer standards put in place by the likes of Greek2Me, with Support_Updater integration and preload.cs.
I'll be placing more emphasis on developing features oRBs doesn't have so that we can do better for the community as a whole instead of being direct competition.
