wow, seems like everyone is having this issue.
I currently use the chrome browser. I played around with the settings last night and I found that when I went to "clear browsing data" and deleted the cache and cookies, I was able to see the followers box.
I tried to view my blog this morning and it disappeared again. Deleted those 2 things again, and it came back. It really sucks having to delete each time, so I'm hoping they realize something is going on and it gets fixed.
I tried this same thing on Firefox, and it didn't work :-(
