It looks like blogger went crazy and switched a whole bunch of people that were following blogs to anonymous. Those don't show up on your sidebar anymore. 60-70 of my followers were dropped today.
It even says that ALL the blogs I'm following, I'm following anonymously and I'm having to change it back to public! I think that you all are still there and can read it, but I'm not sure.
Please go through all the people that you follow and make sure that you are following them publicly! You have to go through and do this manually. If you need help, please let me know!
Just go to your dashboard and click on MANAGE at the bottom left. Then go through and change all of the blogs you follow to public instead of anonymous!
