As a keyboard guy, if I can't hit enter and have it do it's thing (it looks like a form) I'd be hard pressed to use it.
See my other comment. But yes, I'll add the ability to click Go with enter.
The front-page here is just to explain what it is. Use-case:you are sharing a url that you know will be the first search result for a simple word, so you just share http://bloo.tk/simple+word
You might be hitting enter instead of clicking go. The form isn't actually a form and I'm using JS to trigger the redirect on clicking the link, so the default enter behavior isn't active.
