I've often thought that the whole mainstream debate thing was about resources than about acceptance.
I mean, so many of us here, depending on generation gaps, are pretty much used to and comfortable with keeping the tickling fetish/philia thing secret: it preserves our unusually sensitive-to-judgment natures AND lends an air of "naaaaaauuuuuuuuuuughtiness" to the community, which is kind of a thrill.
But at the same time, as MTJ, Agencies & Achilles Heel Art have demonstrated, there's always been an interest in having the community materials of a higher grade than say, crudely drawn crayon pictures and grainy home-movie-camera S-VHS camcorder videos. I think we've always wanted the kind of professionalism and quality control that is afforded the mainstream but without the exposure.
And contemplating mainstream is one way we've thought about how it could happen. The aforementioned companies above have been experimenting with that kind of expansion quite seriously for the last 2 years now and I like it. Not to mention the work that AddieJuniper and her kind have been doing with videos I think the future looks brighter once we get some film students delving into the adult fetish world and graphic design artists who happen to draw their own Vellicatrices Unlimited fanzines in their spare time.
But until there's a massive cultural shift of introspection and understanding about the kink communities similar to the sexual revolution--but hopefully without the chaos, drugs, government overreaction and shitty, pretentious, self-absorbed politics and music (Emo's bad enough as it is)--any attempt at tickling going mainstream is not only unlikely to happen outside of producers who are aware of it, but is going to be disastrous.
I mean, can you imagine the kind of fallout that would occur for PARENTS if tickling goes mainstream during the "To Catch A Predator" pedophile paranoia phase our culture is going through right now? You'll see a whole generation of new members who have NO childhood tickling stories or memories at all...come to think of it, I wonder how these hypothetical members would even become aware of their interest.
