If you don't move past the first page, then you must not be that interested in working for deals. Using right now as an example, the first page contains bumps from 5:05 PM - 5:20 PM. That is 15 minutes worth of action. Are you telling me that if it is older than 15 minutes, you don't care to go looking? I'm sure those times increase and slow during heavy and slow times, but it's a weekend and the middle of the day, so I am guessing it's about average.
As for items being lost within threads, there is a search function that I assume people use to find what they want. Again, good items will be found by those wanting to find them. I'd suggest working on creative titles that grab the users attention.
I believe that there are not collectors here that are active enough to see it, for everything that shows up. The site has many users, but many are inactive or infrequent visitors. Hot items will get the most action and some will never see any. It's similar on ebay. Sometimes items will list, be visable for 5 days and end with little fan fare, even if you expected more.
My perfect example is a bat card I won last week, numbered 6/20, a jersey number no less, for $0.50 plus $3 s/h. Not one other version of this card has sold for less than $10!
