Is it odd that I've spent like 100 hours here, but have only 13 posts?

There is a lot of knoweldge here. Considerably more than you will find on the average internet debate forum. But as well as it's resident experts EvC has it's fair share of brazen blaggers, articulate wannabe's, post-it-and-see hopefuls, pet theory pretenders and outright loons. With everything in-between. Furthermore different participants swap roles depending on the topic in question. So you might find yourself marvelling at the profound insight and clarity of expression of someone you agree with on a social issue and then find yourself confronted by that same person in a thread where they are seriously advocating the actual existence of Daleks or some such (I exaggerate only mildly). My advice is to get stuck in if you are at all tempted to. I personally think I have learnt much more from participation thatn I ever could have just from observation.
