Show HN: Crowdsourced annotations for arXiv articles

I wanted to make something like Fermat's Library [1], but not limited to only a selection of articles. This thing actually works for any PDF file, even local files.

Now the problem is how one would promote this and get users.

Feedback?

It's a great idea! Not sure what else is already out there; aren't there a number of pdf annotation sites? Not sure if any are targetted at arXiv. The interface is nice; is PDF.js easy to mod?

But where's an example of an article that actually has annotations? I clicked on a couple of article links on the main page, expecting that these would be the most recently annotated articles. But I hound no annotations. I assume that if it has annotations, you can view a list of them? Because, that's really important to have

I know hypothes.is supports PDFs, but their annotations work on selected text ranges and that doesn't work very well for math stuff (hard to select).

The main page has recently listed arXiv articles right now, we'll add the recently annotated articles soon.

As for PDF.js, it's pretty well written and easy to understand. I didn't have trouble make modifications at all.
