Having issues to log-in. It's not very stable at this point in time but it's a great initiative no doubt! I hope development will make this add-on more user friendly soon.
Having a second citizen-owned layer on top of the regular web will be one of the major steps in the future as it flips content- and discussion-control on its head.
The basic functionality seems to work, but the extension still has some rough edges. For instance, global comments (introduced without previously selecting text on the page) aren't shown even when clicking the eye icon, but they do show up if one enters a new comment. Also, selecting a text with the sidebar activated shows a little pen icon -- a tooltip would make it clearer that this icon is meant to introduce a new annotation. Highlighting and introducing local comments in pdf documents doesn't seem to work yet, but at least the extension doesn't automatically load all pdfs with PDF.js anymore, which confused me previously. A common UX defect: when trying to login, it isn't revealed whether the password was incorrect or the username simply doesn't exist. I don't think obscuring this information from the user provides as much extra security as to justify the user frustration when an attempt to login fails. All in all, the extension is still in a phase I'd call beta, but the developers are actively workign out the issues on github, so I expect it to keep improving.
