Ok, here is a thought that may work...
Rather than each and every individual recommend of a post shows up, how about it get coded so that for every 3 posters that recommend a post, that post will be given a symbol (noooooo...not a $....too confusing on RB as it is).
How about a thumbs UP symbol?
Conversely, to alleviate the undesired posts how about a "NON RECOMMEND" feature. Working it the same way, if 3 posters choose to "NON RECOMMEND" the post gets a thumbs DOWN symbol.
We must continue to think about the real reasons people read message boards. They want valuable informative information from posters that others agree with.
I think that a poster with enough thumb DOWN symbols would start to recognize that others don't share their philosophy regarding the sincerity, honesty, or very integrity of their post.
I hate it when I think this hard.
