[WARNING if you do not like rants stay away]
First off, the open net is dead, people not giving a fuck killed it when they simply said yet to the shitty deals the unscrupulous companies offered. Those tech savvy should have lead the way away from these sites to alternatives - that didn't happen.
If that wasn't enough the knowledge of EchelonV killed it. People will never again act truly honestly on the net, which hopefully will offset any short sighted plans google and NSA has to premeptively steer public opinion.
The last real breath was drawn as people kept on using google and that breath was drawn precisely when google "modified" their algorithm to kill off private sites who came in high on rankings.
Since then any site that has arisen to challange google seems to have magically have been killed or taken over (suddenly swapping to using google coding for unexplained reasons). Oh to mention a few; scroogle, qwant, lycos, zapmeta, qwant, wn, millionshort, gigablast, xirkle...
You can still search through the old altavista pile if u want but yeah. Most other motors gives u a shitstorm of companies that you do not care for before you can read private sites off enligthened people who strive to improve x thing.
The next terryfying thing is as what happens when large sites get taken over and the large libraries of knowledge falls into informal hands or simply disappears (IMDB boards to mention a recent setback, and i meant the positive discussions not the large clusterfks of idiots and astroturfers et al).
And of before i forget - as someone who saw through FB before it took off (previous avid user of ICQ, AIM, newb at IRC etc) i fucking told you (if any of those i actually told would stumble across this).
Localised meshnets could have been the future (with "netbrowsers" as the tool to reach em), though with the thought of all that information being in the hands of normal people governments are "finally" reacting and starting to spread fibre as far as i know through some of europe (scandinavia) which could effectively kill that effort.
So start taking political action for a free future of information \/.
