This is where I collect and write things, mostly on academe and artificial intelligence. Established in 2010, by Vaishak Belle.
I haven’t used this yet, but this kind of thing would be great for tracking the many papers I come across. Ideally highlight something in the paper and months later, use this to remember the idea, discussion, result, whatever. I think zotero and bibdesk tries allowing for user notes, but it always feel cumbersome because I’m doing most of my discovering on my browser.
