Shouldn't [tag:money] be the "lead tag" rather than [tag:currency]? They are currently merged with the latter as the "lead tag" and "money" as a synonym.

But at least to my "currency" pretty much means the actual cash money of a particular country and many of the questions so tagged are talking much more generally including credit cards, debit cards, ATMs, etc. I think [tag:money] is the more general term which would better suit such general types of questions.
