Are you the founder? (If you are, we have 11 things in common!) This is a really neat idea, and the post does a good job explaining it. I just signed up and I'm playing around.

A brief note: the "Show me [Safe for all ages|Moderate\Unsure|Restricted] overlaps" is awkwardly phrased-- if I select Restricted, is the site gonna be all sex, all the time, or will I still get the unrestricted overlaps?

Also in that little settings pane, having to click OK after selecting from a dropdown is annoying-- I expect it to work like other dropdowns, where it stays like I left it if I click somewhere else.

I like that after searching for an overlap and not finding it, I can click "New Overlap" and it auto-populates, but does that need to be a separate text field? The transition feels a little awkward, and it needs to be very smooth to encourage people to create new overlaps.

I'm still playing with it, but I think it's a very neat concept that could get big.

EDIT: Okay, if I "Me Too" and overlap, I get to see who else did too, over on the right, but it's still one more click to open up our overlaps, a scan through the list, some typing, and another click before I can send them a message about how we both like Nutella. What if there were a message button by each person that I could use right after I "Me Too" something to talk to them about it?

Sorry if this is disorganized and long, I'm just adding as I go through the site.
