Specifically, ad format. What's more effective, listing multiple bikes in one ad post, or starting a seperate thread for each one. I see both done. Let's say, for the sake of arguement, that I want to dispense with a large chunk of my fleet and focus on the bike projects I really want to spend time on, and was thus inclined to sell 10-15 bikes. One listing would be easier, at least initially to keep up with. But maybe individual listings are more likely to draw people to the ads. Thoughts?
