On both accounts, it was reasonably favoured that something ought to be done about it. Looking at the questions, the only constant among them is the occurrence of the word "contradiction" or one of its derivatives in the post. That makes the tag useless for both favouriting and ignoring. And indeed, it currently does have the grand total of zero followers.
The prolonged existence of this tag is increasingly bugging me. The continued unclarity about the scope of the tag (as exemplified in the other thread) and its very ad-hoc use make it a perfect candidate for burnination.
Bring Trogdor, I say!
Update: Given the vote tally, it's time to put things ablaze. (Insert maniacal laughing as deemed appropriate.)
NB. There are some questions remaining carrying only the contradiction tag; these will have to be attended to. All such questions have been attended to.
