I am not on reddit. But I do read it a lot. I usually spend a couple of years before I make yet another account somewhere. Because most of the time other people have made my point and I do not have anything to add. At this point it has saved me many security breaches. As at some point the company almost always loses control of its password database for some reason.

this. the zero barrier to entry thing is what sucked me in. I use it multiple times a day for work and for social/news/entertainment...

I dont use FB at all because of in part the barrier to entry.
