we don't see this much with furniture and larger items on FB marketplace b/c people don't want strangers coming to their homes for pick-ups (regular warnings from the local p.d. to meet up in public venues or their parking lot) and to do that they have to transport it which is not worth it with the number of flake-outs on meet ups people report on the marketplace (people either hang on to the stuff or if they have a means to transport they take it to a charity shop).
Yes I already addressed safety with FB marketplace in a prior post including meeting at designated safe areas which are normally police stations. But to your comment you even gave an example of a rake. I'm just saying it's not quite as common to just have your neighbors offer you stuff or your friends and family to have stuff the same it was in the past. We have a good relationship with our neighbors but chances are if they have anything that we might want if we were start completely fresh it would have already been listed online for sale, free pick up, etc. Many of us started out with hand me down stuff but that was a different era. Garage sales here are still pretty big way to get rid of things if outside of online especially as many neighborhoods have them as a big event in the spring so someone doesn't just have to set up only their house for one you'll get more traffic that way.
nextdoor hasn't caught on here-people are very concerned with their privacy (I personaly question how it's set up in the first place-i've gotten multiple emails saying I was invited to join up but they were from neighborhoods in states I've never lived in or been associated with in my life).
In the 'burbs here it's been as popular as ever, even the privacy concern people have accounts they just complain about privacy while on the site lol. I set up our Nextdoor as soon as we moved in in 2014 and the predominant posts outside of your normal neighbor rants is things to buy, sell or donate although recommendations for services are also a top post. Same with eNeighbors. In my neighborhood the official communication for 99% of HOA stuff all is done through eNeighbors and they tell you that when you are invited to join online if you don't you'll lose out on necessary information. The only thing you'll get in the mail is the dues notice or I suppose if you get an infraction.
Like this was on eNeighbors on Sunday

Quite a nice table honestly at an amazing price, was sorta interested in it but realized we'd probably want one with 6 seats and this one was only 4.
Nextdoor does tries to keep these types of post in the "For Sale & Free" area. Like in the last 30mins in a 3 mile radius there are 45 different things listed including a large sectional, a wooden corner hutch, a tv, several board games, clothing, shoes, some Christmas decor (must be going through what they want to put up), kids toys, etc.
My point was really someone could totally ask friends, families and neighbors but the days of that being a very reliable, easy given of a choice are mostly over. Obviously in your area people aren't as keen to use the internet the same way but it's the predominant way here. I could ask some friends or family for stuff but chances are they've already posted it online even my mother-in-law has posted numerous things from her garage including big furniture items on FB marketplace to sell. It's a good suggestion what you gave it just wouldn't be as successful in my area unless someone is getting it directly from their parents still.
