As they say, there are lies. damned lies and statistics. Don't read too much into them. After all, how do you place a weighting on useful posts, banter, humour and 'nothing to do with model boating' posts? Some members just want a social chat room.
Basically, a relatively few people post useful and knowledgeable model boating stuff while a lot of others simply read the forum as 'lurkers' who either don't feel they can contribute, don't want to participate or are simply hoovering up the pearls of wisdom. A minority like to stir up mischief. It's the same with all forums. We should cherish those who freely give of their knowledge and time and enrich the modelling experience of the rest of us.
