I am not sure how many are familiar with stackexchange, but if someone was able to start a proposal for a coin Q&A and get it in beta, a lot of the error posts might navigate towards that. However, it might eat up newer memberships. On the other hand the retention rate here might soar because it would be those that are hooked on the hobby itself and not errors.
I'm tempted to buy a copy . . . my only reservation is that updates couldn't possibly keep up with the pace of new discoveries.
...but then all the newly-rich with their parking-lot treasures would have to hijack existing threads.
I know that's the standard response to the idea of minimum post counts. Would newbies TRY to threadjack? Yes, but only once . . . IF members are willing to police threadjacking and employ a zero tolerance policy. It's like doing the tango . . . it's takes two to threadjack. Ignore the threadjacker, or better yet, call him/her out, and the attempted threadjacking might be over as quickly as it started. Meanwhile, during the course of spending time on the forum to accumulate X number of posts, a few of these newbies might get a clue that all they have is a damaged coin and will never start a thread about it. That's my theory, anyway.
