Regarding monetisation - I've tried getting into Google AdSense but they would not like the content on the website. Tried a few other ad networks but they all looked like crooks and just decided on keeping the whole thing ad free for the time being :)
Most of the traffic that came in when I was working on it came from Reddit. Looks like, currently, the traffic also comes from mostly Reddit (over 40%), Twitter and Facebook (9-10% each).
Currently, the traffic does seem to have settled and is pretty low. But that's considering that I'm not putting any more work since I'm more interested in newer projects.
Thanks for the extra info. I am working on something that is not a million miles away from your product (http://klavado.com)
Yes, mine is focused on places but the core idea of easily polling people without creating an account is similar. If I bought your site, it would be mainly as a way of gaining traffic for klavado. I haven't yet started working hard on getting traffic so I don't yet have a good idea how hard / easy that will be.
Perhaps after I get a better idea of how things go with klavado, I'll be in a better position to discuss something.
How are you getting your traffic and what is the trajectory?
