Ask HN: Feedback on my real-time image board

This week I've been working on a real-time image board using AJAX long polling and various other JavaScript techniques to achieve hashbang navigation between pages (entire page doesn't need to reload). Pretty much everything is loaded dynamically without a page reload.

When there's a new post in a thread, if you're viewing either the thread listing on the home page or are inside the thread itself, the new data will be pushed to your browser and update in real-time.

It's still in its early stages, but any feedback (critical or otherwise) is appreciated.
