Show HN: Approcity - Hackers helping hackers get users

If you're like me, your number 1 problem is: How do I get users?

Approcity is a totally free link exchange network for web app developers. Feature a customizable (and non-blocking) bar on your website / blog / girlfriends site. When anyone clicks an app that is featured on your bar you will be rewarded with karma. Karma gets your app(s) featured on other people's bars. Its reciprocity for web apps! I've also included some safeguards to prevent the overly-clever from unfairly racking up their own scores.
