Facebook has taken up much of the local classifieds business that Craigslist took from local newspapers 15-20 years ago.

For me, the most effective directory of contractors is through Facebook. I hate it, because Facebook does a bad job of building and presenting that directory, but it's the largest and most relevant one.

Would they? If I'm looking for a restaurant, and Facebook suddenly disappeared, I'd still be looking for a restaurant. I just would have to use Google Maps or something to find one.

I find it absolutely crazy that neither google maps or yelp can use location (geofencing) as part of their "relevant results" algos.

(This might have improved since my last road trip, late 2019. YMMV)

Many times they don't work from a physical location, they do, but a phone number is harder to keep track of than Facebook messages
