If you use Google Reader then sorry about the feed
spam. The problem occurred since I switched servers
to another one, and all my domains were mapped to the same IP/website
for a few minutes which messed up the feeds on Math Fail. I did fix
the feed, however, in Google Reader those items will be permanently
there (in cache) since Google doesn’t remove anything after it’s published :-(. I don’t know about
other feed readers, but the actual feed is fixed and has those items removed.
If you’re subscribed to both SM and MF then double sorry!!
My sincerest apologies,
