Seems the new notification system impacted the news feed filtering of the 'switch account context'. I am now seeing lots of activity for organizations I am a member of in my personal context. I guess this is a side effect of 'watching' those repos?
I have also had this happen to me--I am part of a fairly large company on github, so this means that suddenly I don't see anything in my strema except for posts about that company, so I had to unwatch nearly everything in it, which I would rather not have to do.
