GUYS, what kind of niches your website belongs to? I do some research for my university paper on social networks, I could use some help.

I would really appreciate if You spent a little time, just to write a couple of words, I'm sure it won't take too long. Like pet, adult, adult gay, cars, travelling etc.

And if it is not a secret how many active users there are on your websites.

Thanks in advance. Regards,
