This is pretty off-topic, but the title bugs me. It's a pet peeve of mine whenever people put periods after fragments like that online
If you want to use good grammar and everything all the time, fine. But if you're not even writing a whole sentence, or even an idea, why are you putting a period there?
This isn't the case, I know, but I've always imagined that grammar national socialist's do that when their uptightedness about grammar eventually develops into ocd of capitalizing the first letter and putting a period after everything, lol
