So far it's worked....I think that EVERY regional has a thread that is titled something along the lines of "don't come here" or "if I had known".... heck...if you spend time jump seating, you will find that even the majors have unhappy pilots....but the grass is always green on the other side of the fence....
If people are realistic, and understand what the job is, I think they stand a better chance of some level of happiness and satisfaction. Careful selection of routes based on factors important to the parties involved is important. For me, that means varrations in schedule to prevent route-rut, and on some runs, as eluded to the company tag-line, "delivering more than cargo", I help to fight a deadly disease that kills many, one that took my own mother years ago, so there is an added bonus of an intangible feeling of doing something to help others.

it's in everybody's best interest to use these threads to try to do exactly that, so people aren't blindly going to companies, then jumping ship, creating large training backlogs, and making shortages of flight crew worse, and potentially reducing first year pay everywhere due to turnover.
Idealistic, maybe, but honestly more realistic IMHO.
