The short answer
Should I use big or small online groups to find buyers?
Small ones. In a place with 80,000 members, your answer is buried within an hour. In a place with 200 people who do the same job, most of them read it, and by your third answer they know your name.
One thing
In a place with 80,000 members, 50 posts go up an hour. Your answer is gone before lunch, and nobody remembers your name.
In a place with 200 people who all do the same job, a good answer gets read by most of them. By your third, they know who you are.
Big feels safer. It isn't. Small and boring is where you get noticed.
