Show HN: VisSense.js – Library for observing visibility changes of DOM elements

You'd do me a great favour if I get some feedback on this project.

Thank you. I know that :] ... but it is not all about the looks.

Is it easy to understand/use/integrate? Do you think it is well designed/extensible/developer friendly? Too many questions.. unanswered.

Anyway, thanks for your comment :]
