(Let's not count e-mail... pretend they're on Outlook, thus, not needing to use a website anyway) YouTube.com
furaffinity dot net, because i can post my art and communicate with other artists about it (theirs and mine) on the same page with what i'm looking at or posting. truth is, there are a total of three or four sites i visit routinely every time i log on, to see what's going on in the aspects of the world that interest me, that are more useful to me for this then anything on mass media, by which i don't mean to discredit their efforts either, though media's idea of entertainment is mostly crap. the first one, even set as my home page, is again fur affinity. second stop is here. then railfaneurope dot net, for train pictures from all over. then rapping it up, my nations of cameroi and nolo gap on NationStates. youtube gobbles up to much of my alloted bandwith, though i do see things on there, well for every interest, but i don't like how it has evolved into more of a media outlet then the place it started out to be for ordinary, not ready for prime time people, to share their own animated creativity. vimeo is still closer to that, and where i post my own animate bits from time to time, and not nearly as often or as many as i would like. also my ability to log on to youtube mysteriously disappeared several years ago, with no explanation offered or given. i can still watch, just not post to it. and no, i didn't troll or grief, but no doubt i may have inadvertently offended those who do. yes i would much rather watch home grown animations people make of train rides and little furry creatures, even archiology and other odd things, then idiots with guns and cars beating each other over the head, which seems to be televised media's idea of entertainment these days.
I enjoy this place a bunch... PornHub is gold.... However, as a fan of all things internal combustion and horsepower I'm saying Yellow Bullet. Technical is cutting edge, elite and professional. If you want to wade into the other areas, wear steel toed boots and leave your fragile feelings at home.
