1001+1 internet services

Lately, I keep getting a new invitation every day for joining another super-duper-exciting-innovative Internet service that will forever change the way you surf and think of the net.

Sometimes I get excited, some others I am so damn bored of just clicking again to find a service which you need to read 3 pages to understand its way of use, which I don't have the courage to do so anymore...
Nowadays, every single idea or last night's bad dream ends up in a new developed service, new ambitious developers-dreamers-entrepreneurs drop like flies, that’s the real freedom of the Internet.

So we are in a continues loop of evaluating new products, and I mention most of my findings on what the Internet offers in "centralized" & user-oriented services...

Please help me out in WHICH DOES WHAT WHICH DOES WHAT OR YOUR EXPERIENCE EFFECT (Can't expect it all from one poor mind). So, lets start:
