Admittedly I can't back up my 99% claim (so it could be vastly exaggerated) but I would be very surprised if the percentage of useless posts was under 50% (am not sure how we can prove this though).

Personally I am opposed to people getting paid to post at all but maybe that is also because I don't get paid to code (yet put in generally a hundred hours per week of coding effort).

And yes - I won't continue a discussion with an ad-sig poster any further (he is welcome to create an alt to join the other topic - but like most lazy ad-sig posters he won't bother).
