Hypothesis might make a fine alternative to Twitter.

• Is anyone using hypothesis in this way yet?
• What would be a good tag to distinguish "tweet" Notes?<br> (I guess it would be cute to use "tweet" as the tag.)
• When there's not a specific webpage involved, what would be the best URLs on which to attach such a Note?<br> (I suppose any page of your own on a social media site or blog would do. I also see that we can annotate pages on local servers.)
