I am happy to moderate that community, but I will also tell you that my main purpose in joining it is because I'm really curious about where the project goes more than because I want to contribute myself. Moderating isn't the same thing as contributing and, as I said, I am happy to moderate.
I agree that a moderator for that community shouldn't require someone with a heavy computer science background. It just so happens that I actually do possess a heavy computer science background. :-)
If you would like another moderator, I would recommend that you also ask foxfirefey. She is one of the most even handed moderators I've ever seen. She has done an amazingly good job with the no_lj_ads community and kept it from becoming a community who's sole purpose is to rip on LJ while not alienating any of the community members. She hasn't joined forklivejournal, but if you ask her and say something similar to what you said to me, she might join and help moderate it.
Another suggestion I would have is that if you are really serious about this, and want to get people on board, that you pick a name for the forked version of LJ that reflects the goals in forking it. You will attract a lot more people to the project by making it a project that's attempting to achieve something rather than if it's just a project that's perceived as simply existing to avoid a negative.
