I don't really care at all about gemini but I love love love all the stuff that shows up around m15o's' projects (link). the newest is vpub (source) and it's real cute, makes me want cinni to do a UI theme. Also apparently there's a feature in atom to specify emails where replies to posts can go, which is nice. :)
my annotations look much cuter on lindylearn.
I'm not really adding notes about the things on which I'm doing my most focused research. That's because I'm hoping they'll lead up to a project that -- well, I'm a little obsessive about wanting to keep it cleanly pseudonymous and not to be traced back to me. This is a strange concern when I'm pretty sure there are fewer than six people who will ever pay attention to it... but oh well.
