If you allow me I could design a rough template for a new site and share it with you. As already mentioned, this project has great potential and all it really needs to grow is more available work, which can be solved by using different language and terminology on the landing page. I can do that for you.
Jorijnsmit, I think it needs more than that; if you're aiming for average bitcoin-joe-on-the-street to be able to use vanity addresses, even copying and pasting the private key into a website/app key-import text box might be more trouble than they'd be comfortable with. Certainly if they generated the key on a website then had to import it into a phone app (or any other device), or the other way round. The ideal would be a point-and-click interface to "download" the key and apply it. There's no mime-type or file format or filename-type-extension set up for that, and no apps I'm aware of have considered to make it easy enough to do anything like that. Because of the low demand for usage of that kind of feature, I think - bit of a chicken and egg type problem.
Are you talking about importing a private key? Because in that what I think you are describing are QR codes. Of course not all smartphone apps would support this, so some people would just have to retype the private key or copy-paste it somehow.
Anyway I do think Vanity Pool lends itself very well for providing keys to bitcoin-joe-on-the-street guys, if the site is presented in a different way that is.
Do you keep (Google) analytics statistics ThePiachu? I wonder what your bounce rate is, e.g. how many people decide to visit the site but close it after seeing the front page. The bounce rate for the "request a vanity address" page would be even more interesting.
I never heard back from you on some text I rewrote for the front page...
