Magazines are unfortunately a dying.. breed... I guess, because of the internet. Why buy something in print, which costs the authors money, when you can get it and publish it for free on the internet? Blogs are seriously starting to outweigh magazines in terms of influence too. More people can access a blog than a mag.
Kinda doesn't surprise me there aren't many FG mags because the popularity of FG riding sprung up during the rise of the internet generation and it's not likely that it would've developed in print when everything was already online... Unlike other bike mags which have existed since before the internet and probably have developed a means of sustaining themselves.
We as a community here could easily start a sort of definitive blog about FG riding... There are plenty out there but many of them are just one guy with one opinion, which is kind of limiting. One will be anti-hipster, anti-tarck, one will be catering to that lifestyle... We could do one with both, make it picture heavy, etc. Just an idea.
Zines were the method of subculture literature in the 80's and 90's, and like it or not, blogs serve that purpose, perhaps even better, for this decade we're in right now. It might be better not to resist the change and instead embrace it. I dunno.
