Whilst your point is valid, very valid - I myself have been guilty for pulling up newbs on this - contribution is what counts here. There are plenty of members who have not posted a review but have made the effort and contributed. Some of of it useful, some of it not so useful, and some of it well deserving of the rebuttal it attracts.
I myself am not a seasoned or veteran punter, for me it's not a numbers game or about variety and/or trying someone new. In fact I pretty much only see the same lady for my 'meets'. But I do try and contribute positively where I can and pitch in with observations, local knowledge, any experience I have benefited from, and from time to time the odd bit of humour and sarcasm.
However, although you have not posted a review in the 18 months you've been a registered member here, neither have any of your posts actually contributed positively to the forum or contained any substance to be of use to your fellow members here. All you've done is latch on to a few forum threads and posted some inane, glib one-line responses that amount to sweet FA.
Why not try actually contributing positively - doesn't have to be a review- instead of preaching and become a useful part of the forum rather than just whinging?
Just a thought, eh?
