Giving Diigo a fair shake. Turns out, it might be cool for active reading. I still have issues with it (comments are private by default and they don’t disappear on pressing "enter"), but the main usage pattern seems to make sense.
So… Actively reading this Dare Obasanjo blogpost about technology adoption. Found the link thanks to @audio on Twitter.
All of it is very "knee-jerky" («réactions à chaud»), on my part. I like that. More RERO. And more efficient, I think.
BTW, a major point developers should understand: users should be allowed to be lazy, sloppy, careless, and thoughtless. Can’t remember the term but Blacktree’s QuickSilver had a whole explanation about "not thinking." I think enough already that I don’t want to think about my use of tools while I’m using these tools. A good example of where a problem may appear: forcing users to add tags or forcing them to edit a preview version of their comments. I see why it would make sense to "incite" people to do this. But there’s a context for everything and forcing users one way or another is very patronizing.
