[wp-hackers] Change Tag Delimiter from a comma to a semicolon

[Jeremy Clarke]

This is pretty wacky man. I suggest you reconsider your decision to include
commas in tag names. Is it absolutely necessary? Would the text content
really not make sense without the comma? If you're tagging book/movie titles
or something why not just skip commas, are you afraid of the hipster
title-spelling police?

Have you considered using categories instead?
