I'm going to join in with having "newest" be default is frustrating. Having to toggle to "oldest first" each time will get old fast.
1) Please switch oldest first (your old default) back to default
2) For the users who like the newest first have it be a setting we can change in our settings so both camps can be happy.
Like the OP, I'm also having trouble with a few authors I follow flooding my feed with "Thanks for posting" I would love an option so I can choose what to follow on a by author basis. So I can choose if I want to follow that authors comments and articles or just the articles. I normally follow someone because I like their articles while other authors also jump into the comments thread for a healthy debate.
