Interesting, the linked article says this:
> Vanguard Federal Money Market Fund (VMFXX) is the settlement fund in a Vanguard brokerage account. You don’t have to do anything extra to buy or sell this fund. It requires no minimum investment. Any cash you transfer into your Vanguard brokerage account will automatically land in this fund.
I didn't know that. It definitely has better returns than most savings accounts. Instead of parking money in a savings account you could just leave it there until you decide whether to invest it or transfer it out to do something else with it.
Yes. By the way, this is an unusually good deal for uninvested cash at a brokerage (it's not generally a reasonable thing to do outside of Vanguard). E.g. Schwab makes most of their revenue from interest on your uninvested cash.
