Oh, I should mention the bookmarklet, though, which allows submission of sites: http://ycombinator.com/bookmarklet.html http://ycombinator.com/bookmarklet.html. I don't use it, so I'm not sure if it upvotes already submitted stores. But I guess you could use its infrastructure to make a button. Something like: <a href="http://news.ycombinator.com/submitlink?u='yoursite'&t='yourDesiredTitle'"><img src="http://ycombinator.com/images/y18.gif" /></a> (untested)
