Firefox is unstable on Linux, as best as I can tell, only because of either extremely poorly written add-ons or (especially) the Flash plugin. Personally, I prefer Links in graphics mode, since I like my webpages more often without a lot of flashy bullshit.
My concerns with Chrome stem mostly out of the massive privacy concerns, hence the brilliance of the NSA comment. 'Anonymous mode' is no substitute for customizability. My Firefox doesn't leak referrers, can get plugged into Tor with ease, doesn't run scripts unless I tell it to, and has the Web Developer plugin. Meanwhile, Chrome is doing shit like reporting back all the websites I visit to a centralized database.
Use your damn heads.
Excuse me, but isn't playing paintball in any sort of situation where cover is provided essentially identical to a combat situation in every way except how the gun fires? Do you not have to remain stealthy when possible, find cover when available, camouflage yourself, and anticipate your enemy's moves?
This is not to say, of course, that banning paintball will reduce violence in any way. In fact, that's the stupidest goddamn thing I've ever heard. Letting people play paintball encourages them to play paintball. If you want a reduction in violent crime, why don't you fix the broken economy so people don't have to rob stores to eat?
