Oh.

So I didn't give Mint.com a fair shot. Apparently you can take a more detailed look at all your transactions and assign different purchases to the appropriate categories (thank you Sarah Telson for allowing me to hover over your shoulder while you did this on your account). This should solve that pesky "uncategorized" problem - provided, of course, that I actually take the time to look over all my transactions and categorize them appropriately. This would be a lot easier if I didn't pay for $1 tubes of toothpaste using a debit card while simultaneoulsly paying for my share of the groceries by covering my roommate's bar tab for a weekend - but I'm sure I can figure it out.
