I switched to https://ynab.com a while back. It's not exactly the same concept as what Mint was intended to be, but I couldn't be happier with the move.
The best part for me is how it handles where money you earn goes, it always goes to next month, not the current month (granted, after I graduated college it took me a bit to actually get back into this because of living with effectively 0 income for 4 years), so you know that you're already budgeted for the month when you get into it. That feeling is super comforting for me.
