I'm not sure where Mint gets its "averages" (other Mint users?) so I usually don't look at that, but I have a great time comparing my own recent, thoughtful spending against past, spendy-pants numbers.
For instance: for the last six months vs. the six before, my grocery spending is up 39%, but my everything-in food spending (groceries, restaurants, coffee, alcohol) is down by half. Very pleased indeed!
Overall "shopping" is down 80% in the same comparison--very pleased with that! (Though also appalled at past!me ...)
Anyone else compare their current, mustachian selves to their past spending on Mint?
