Looks like a take on Cloudapp, http://getcloudapp.com/, but free and supports up to 150MB transfers. Cloudapp is free with premium features that supports up to 250MB and is dominating the space.
It doesn't look as though Kicksend is useful for URL-shortening as well, which CloudApp makes dead simple.
I am curious, though, to see if/how the guys at CloudApp respond to this...
