I get like three notifications for certain people. In one case, it's cause I've followed/unfollowed too many times, but there are a couple other people for whom this happens that I remember doing no such thing for. I'm gonna go look at the Blogs tab to see if I missed anything else. 

I've never unfollowed anyone and I know I only added Dan once on the day he signed up. I know I've seen peoples followers lists where someone appears to be following them 50 times but I don't see that on my account or Dan's. 

I get double notifications for almost all blogs. Today I got FOUR on one of them. I always imagined it was caused by someone editting a blog after posting it live. To save the changes, you have to post it again. That's why I try and make sure I've got everything right before I post. But I'm not sure that's really the cause, I just imagine it to be so.

After saying that I now have a double notification fom goaztecs for the first time ever.

I get this for every one of your posts. Thought your were just a dolt :p

I am.

I've gotten a few double notifications, and occasionally a few that just redirected to the homepage for some reason.

I haven't recieved any double notifications. I guess I'm not following enough people.
