Well, to my naive way of thinking, there's your first problem. You've done the usual thing of creating a site, and then wondering why no one turns up. You need to "market" your site.
And that doesn't just mean telling HN about it several times. You need to create content, you need to get a few people to play with it, you need to make sure they immediately find something interesting and useful, you need to engage with them, etc.
And to me, the problem is as I say in my other comment - I don't see how tagging items with language names helps. Binary Search is Binary Search in any language, and most of the important and interesting things to say have nothing to do with the language of implementation.
So you have three problems:
* Content - you need to work harder to create more
* Marketing - you need to get a few users who immediately see the value
* Tags - I know they are the basis, but I'm not convinced language tags are the way to go.
YMMV - I'm often wrong - free advice is often worth exactly what you paid for it.
