I don't know if the site is totally responsible, because also
my blog also really motivates me, but I'm saving about $850 per month. Yahoo!
$600 to workplace retirement accounts (my spouse's and mine)
$75/month to college accounts for my almost-3-year-old
$150/month to ING for irregular bills. (I expect to spend all this money each year)
plus the occasional small deposit in the ING account to boost my E fund savings.
Still want to start saving monthly into special accounts for gifts (xmas, bday, etc), charitable donations, travel, and a car fund. I also want to start contributing to my Roth regularly. Right now I just put the occasional windfall in there.
