Would I gain any benefit from Truffle by connecting my business account instead of my personal account? I already keep all my business expenses separated. Isn't that what other freelancers typically do?

There's a lot of classes of people that can be considered "freelancer" in this context, from those who basically run as a 1-person agency to someone who just picks up a 3-month contract instead of a permanent role

Not all of those classes will have or even need a full business separation setup

Try it and let us know!

How does it know what’s business related?

It is maximally inclusive. It is up to you to remove what is not.

I know that doesn't cover all use-cases, but it is what we started out with.

this is the best way to do it IMO. algorithms aren't as smart as me at everything. they're going to miss some things. even facebook with all their resources still can't figure out an algorithm that actually shows me posts from all the people that I want to see. And honestly it's easy enough for me to go through a list of potentially business-related expenses and say "nope, not business-related".

Facebook does that intentionally, the more you spend scrolling through crap with the occasional thing you actually want to see the more time you'll be looking at advertisements. They don't make money by being more useful, they just make money from showing you ads.

Presumably the same reason for the recent reddit redesign, and snapchat's awful UI changes.

what I mean is that there are some friends that I never see posts from, even though I want to. Ads aside. Facebook will never show me posts from some people that I'm facebook friends with. I could have 500 facebook friends that I want to see posts from, and even though I view thousands of ads I'll only ever see posts from the same 100 people.
