I'm one of those users! I make a trade at Vanguard maybe every other month! I have another brokerage account I use for more active trading. My Vanguard account isn't "for" that, and the UI is so bad it kind of discourages it.

This is the same way I treat my 401k platform too. I never touch it and only log in to check a balance a few times a year. I opened a RobinHood acct for my own lil side pot and projects that I actively buy/sell on.
