Sail

I don't wish to be negative, but after reading the schpiel, I'm absolutely none the wiser as to what sort of thing this could be - even vaguely - so why would I sign up for early access?

I appreciate not wanting to give too much away during early stages - but not even a crumb?

Is it a browser (I might be interested)? Is it another logged-in social sphere (I'd not be so interested)? Is it a cross-platform filter?

It is very pretty though.
