I tried that one, which indeed seemed to have a potential, but after a few days of usage, I bumped into some issues like: - I can't see the public annotations - my own annotations only show up about 75% of the time (refreshing several times) - small community - somewhat confusing doc I do see an interest in having public web annotations. So I'm asking, are there any good annotations tools out there? What are the references?
