Hypothes.is doesn’t have a social media-like follow functionality baked into the system, but there are a few methods to follow interesting people. My favorite, and possibly the simplest, is to add
https://hypothes.is/stream.atom?user=abcxyz as a feed into my feed reader where abcxyz is the username of the person I’d like to follow.
So to subscribe to my Hypothes.is feed you’d add https://hypothes.is/stream.atom?user=chrisaldrich to your reader.
Of course, the catch then is to find/discover interesting people to follow this way. Besides some of the usual interesting subjects like Jon Udell, Jeremy Dean, Remi Kalir, et al. Who else should I be following?
Ideally by following interesting readers, you’ll find not only good things to read for yourself, but you’ll also have a good idea which are the best parts as well as what your friends think of those parts. The fact that someone is bothering to highlight or annotate something is a very strong indicator that they’ve got some skin in the game and the article is likely worth reading.
