Omegle doesn't have the 'therapy' pretensions of BlahTherapy - it's just a random chat room with either text or video. All my conversations started with the other random person asking 'asl?' short for age, sex, location and an answer of anything other than 'young blonde teen girl gagging for it' means you get cut off immediately while the sad man goes to find someone else (probably another equally sad man) to uh... discuss fantasies with. Avoid like the plague!
However, both of these are as nothing in comparison to Chatroulette, which you may have heard of. The idea here is that you link your webcam up and get partnered with some random person, who you can talk to, or click 'next' to move on. The first two that I got to see where actually webcammed groins, doing what sad male groins do. Afterwards followed click, next, click next. Terribly distressing, hateful and soulless. The internet at its very worst. Really, really horrible. It also made me feel horrible as well - this mindless clicking and dismissing of human beings one after another.
