The question is overall pretty simple! Would you share a hit on your Blog to get a hit from another? Our would you rather keep your own traffic and find more else where. What do you think the chances of possibly losing a reader to this other Blog when sharing the hit for hit idea would be? Cheers! oops: Maybe should have went in general discussion! My bad.....
I don't think you would necessarily lose readers when you share, after all you are going to share with sites that have other unique content.
I think the results could only be positive. But how many people currently do it? I don't see any in link exchange.
