Mint just reached it's one-millionth user! You can read about Tammi K from Oregon on Mint's blog. What I love is that to reward her, and to celebrate having one-million happy users--Mint.com paid off Tammi's credit card, and her mother-in-law's card since she is the one who referred her to Mint. That's an awesome surprise!
A couple of other interesting notes on Mint.com--SmartyPig and Lending Club accounts now work in Mint. Also, if you have assets, you can show them in Mint (home equity, concert posters, cars, etc.).
Lots of exciting development going on in recent weeks with Mint, so I thought it would be worth mentioning.
