To answer the main question this site isn't created because of a falling out with LL. It was created by Doublezero and I doubt he had any motive or issue with LL. I have no problem with LL and still work with people there on projects and help out members as well. It just so happens to have gotten many LL members come over and join. Many of them reported being unhappy with LL for various reasons and wanted to give this site a try.
This forum is pretty new and has went through many changes so far as you know new forums grow and develop. I see your point on having unique feature but from what I know Doublezero and others here aren't concerned about that or even if this site is "popular". I gotten that much from a message from Doublezero earlier in response to a PM I gave him on the subject of growth.
Tell him that this site is for modders by modders. We are focused on providing the best environment for modders to do their work communicate and develop their craft without games, gimmicks or fuss in a positive inviting environment.
Tell him we would love to have him check out the site, ask questions and make a decision if he wants to join. We want those that want to be here and respect those that don't.
This is the same for everybody from the complete noob to a 20 year veteran and yes even LL admin is invited to come and check out the site and make a decision for themselves.
If you have any other concerns that you feel that might not be appropriate for public please feel free to PM me for clarification if I can't answer it I will find out the answer for you.
