It definitely seems supporting or not supporting your LGS (F or not) can swing drastically from region to region. I've been in towns where gamers sigh wistfully and exclaim, "A game store? What is this you speak of? I know of no such thing!" And other towns where it almost seems you can't swing a dead cat without hitting a half-decent game store. Maybe some enterprising entreperneriul (that can't be spelled right) sort should work out some amazing plan to bring some consistency and quality to the industry.
In the last town I moved away from (Psion might appreciate this!), the place had a poor track record for game stores. There was only one example in the seventeen years I was there of a half-decent store, and it's sadly being sold right now (although, as I don't know the new owner, it might not be sad). All the other LGS that opened didn't last because the people running them were, well, idiots. Rude, uncaring, no-business-sense, customer-service-lacking, smelly gamer idiots. (This was at least four successive stores, perhaps more, memory is foggy).
The most recent store was run by a friend of mine who had a deal on rent that helped keep him afloat. When he was in the store, it was an FLGS, when one of the goobs he hired to watch the store while he was away was in charge, service was lacking. While my pal's business sense wasn't abyssmal by any means, he didn't really run his store to succeed in the business world (he may have meant to, but didn't know how). One thing he did that seemed to work really well was to hire this hawt young girl who liked skimpy tight clothes, wasn't afraid of geeks, SMILED at you and asked you how you're doing when you walked in, and had just a little bit of geek in her on her own. After a short time, she had a FOLLOWING and that store always seemed packed (not sure if anybody was buying, but standing room only).
If the hundreds of store closures that Erik Mona mentioned are of the "lesser" type of LGS I am all too familiar with, I am not sad at all to see them go (of course, who knows). It'd be like cutting away dead tissue . . . sure it hurts at first, but maybe you'll live longer and healthier because it's gone. Hopefully the truly FLGS stores are still afloat and doing well!
