This deleted answer was used to comment on the usefulness of the actual answers so was criticised and suggestion made that it should have been a comment, not an answer.
- You need a reputation of 50+ to comment? so this may not be an option
- A comment can only be applied to one answer?, whereas this 'answer' was commenting on the answers in general, not specific to one answer.
So if the facility is not there to make a general comment, is it fair to criticise the person for using an answer the way they did?
