While we're on the subject of plurals, fuse and fuses should be merged. Since it is now impossible (except for moderators) to create tag names that look like singular/plural pairs (it wasn't when the site started), and that's the lot of them, this issue won't come up again.
There's some room to be pedantic about the difference between pins and pinout, but I'm not sure that it's necessarily worth enforcing or cleaning. Right now, vote for this post if you agree with merging pinout -> pins. Otherwise, suggest an alternate course of action in an answer below.
