Signed up! This is really well executed. I would like to offer a contrary opinion to those suggesting to change the name. Outside of a very niche audience, Kismet isn't confusing and is a great name for the product.

Hey, I really like the idea of this, but I don't have time to network everyday, have you considered allowing custom intervals? I.E. 1/week?

Yes! It's next on my list of updates to make.

It is really cool, got a great match right out of the gate! I'd consider embedding people's HN profile right in the emails instead of just a link, it would make the emails more interesting/click-worthy especially if the person's profile is pretty bare. Also second the other requests that 'my' first email shouldn't go out until I have the chance to fill in some parts of the profile, maybe just wait an hour or two? Again this is very cool!

Maybe a stupid question, but shall we enter Twitter/LinkedIn/GitHub handles or full URIs?

Great idea! The landing page is nice and clear.
