I'm sure you've seen it: a "share this" link of some sort on some Website that leads to a submission page at a social news site like reddit or digg. Often, these things include indications of how many upvotes or downvotes a page has received.
What I'd really like is a link like this that actually indicates whether it has already been submitted -- and, if so, how many comments have been made for that submission -- at Hacker News. Failing that, just a simple "submit this" that does the same thing as my browser bookmarklet would do well enough.
I'm not quite familiar enough with JavaScript to have figured this out on my own and, frankly, I'd rather do it without client side scripting if I can, but any help would be appreciated. I feel like I'm missing something obvious.
