Regarding your second question. I thought the landing page and the tour would answer "what it does". Sorry. Obviously, I'd be very curious to know what it didn't tell you. But if you haven't registered, you probably can't answer this question.
I'm not blocking any email domains, so feel free to use some trash mail address, if you want to have a look without sharing your email address.
I thought "meeting people" was quite neutral.
- Looking
- Orientation
- Gender
I realise it's all innocent, it just sets an odd tone.
I am not sure if there is a general social network burnout. Maybe it's specific to social networks with lots of noise, likes, shares, news, ads and so on?
At least one new user told me that this was a social network that he can actually imagine to use.
Re "what it does" - might have been my Saturday morning slowness, but I completely missed the tour link/page.
You could do some tests on the landing page using http://fivesecondtest.com/ to see what others notice and understand there. Good luck!
