An easy free mini webpage (or profile if not elaborating it to make into something more resembling a webpage, it has basic fundamental presets and interface, not highly customizable but fairly good anyway!!!!) and you after sign up you bearly have to blink if you don't want.....See if you might like Thalia (I think most people in the enviroment like it) so to try
Care2.com might light your candle to a degree, not in the way of myspace of course, but take into account that all you need do to set up a few basics --mostly done by presets that you can alter if you wish to improve your look-- and so you can look quite ok, or even blingy, if you add lots of graphics/pic, or if not bothered in being flash which I'm not either, you might like at least like to pick out automatically a displayed picture background from the many schemes dropdown menu, (not all to my taste but hey you'll find at least one u like) which you do after you're signed up and in and all the rest. You can leave your profile (profile aka webpage IN ONE if you will) blank/plain also by default, but nothing is charged at any time, even for having a backgrd to your profile, you simply select one as I outline above.
And then you just partake "optionally, but obligingly too if thinking retorically
as to ask why else go there but to partake" in a site which is socially and for the environment, but its not bad all in all.... so long as you don't mind many posts in groups and such will contain variant size text according to each individuals' posting style, which can be tedious if small, but there is still stuff you can do like CLICK-2-DONATE (part of Care2), like that, which you can do supporting animals etc (donating for free) as one of the things you can do without any hassles you don't want, plus you can also in preferences opt out (or switch off) network messages, so you don't have to put up with hassle you don't want or just don't have time for....
So anyway, although similarity is almost non comparable to myspace,
Care2, however is a strong network (about the only thing in common with what you want I guess, but still) so I know you might not care to know, but just in case it may appeal to you on the side, thought it worth mentioning your way.
