It's an odd platform. They have a lot of great features for outreach and discovery of local events and groups of people, leveraged by the strong network effect. For contact with local groups of people with similar interests, and for planning events, for group communication, it is an effective tool and one that has enriched my life in substantial ways.
The one thing that I really hate is the front page feed. It was probably a great business decision on their part to emphasize microblogging, as it definitely increased engagement in the platform. It also turned everyone into memelords who just re-share funny cat pictures, pyramid schemes and incendiary political propaganda. I tried just filtering that out with the "see fewer posts like this", but I turns out that people just don't really post anything but image macros and articles anymore.
If you've tried it, how do you think Facebook's classifieds compare to NextDoor's classifieds?
Craigslist was tainted by the unsavory element of prostitution and stolen goods and isn’t a resource that I seek out. Facebook marketplaces seem like what eBay was in the 90s.
What's really hurt Craigslist is all the scammers. You can't post anything of value on there without some scammer responding and telling you they're going to send you a cashier's check and have a personal assistant pick it up.
You don't have this problem at all on Facebook AFAICT. When someone responds to your ad on Facebook Marketplace, it's a real person who actually wants to buy your old junk.
In short, the formats of the sites make all the difference. CL was created to preserve anonymity and not be a centralized social network, but that feature is also its undoing because it facilitates scamming.
IME, Facebook Marketplace is far from free of scams and stolen merchandise. That's why some people call it Fencebook.
Thats not a new problem though, is it? I dare you to buy used car parts on ebay.
I actually found some great rugs (owners did not know what they had!) and furniture on the FB marketplace. Much better finds than on craigslist, and easier to verify that the seller is a human.
