Characterizing sub-communities of the NES scene

In this post, rainwarrior pointed out that neither NintendoAge nor NESdev BBS is necessarily a representative cross-section of the NES fan community or of the market for new NES games. Each attracts its own set of "[l]ike minded people": NintendoAge is "mostly a collector's forum", and NESdev members "largely prefer software, especially free software, over tangible things". If someone is considering forming a team to develop an original NES game for distribution on cartridge, what other sub-communities are worth considering when trying to build a larger sample of the community, and what makes each distinct?

Only I could think of is Famicom World or some kind of general Nintendo gaming forum.

Famicom World is also largely a collectors forum (and the closest thing to an English Family BASIC community I guess ^_^;) but very different from NintendoAge (a more friendly air at Famicom World IMHO). It's also a place for people grown up in Famiclone countries that feel more nostalgia towards Famiclones and unlicensed games (crappy or not) than toward official ones, or people that just collect these things for no nostalgic reasons.

Physical cartridges are commonly mostly preferred there too, although unauthorized repros of commercial games (licensed or not) are usually not appreciated there (unlike NintenoAge). Homebrew is welcome though.
