This kind of thing is what makes 12yr old girls get eating disorders... that is, it's more of a social thing than anything else.
... I can appreciate the intent, that newbies might get an indication of who is just a flash in the pan, and who isnt, but I agree with wasp that it isn't representative of trading ability at all. In my experience, most rep is given out for some witty comment or a shared perspective - both of which are no indication of anyones ability to trade.
Of course - the only way to determine that would be live posting of account PnL's, but that aint ever going to happen is it.
... the complications arise, perhaps, because traders are inherently competitive. The rep thing is a game, nothing more. I can (and have) made posts detailing some particulars of my trading style, but these are largely ignored rep-wise. Not to give the impression that I'm bitter about it, because I understand how to play the game. I can spend 10 mins on photoshop with a picture of S89 and get a bunch of rep, increasing my score in the game (which is what I really want to do).
Up for serious content for sure, but i think we all have to be honest and say that no-one takes T2W very seriously. The only serious trading questions are of the "tell me what I need to know to make loadsa money" or "for a limited time only I'll tell you everything you need to know to make loadsa money" type.
I mean, if I am honest, I reckon most of my rep is for laughs / shared perspectives. I have, and will continue to do so, make the occaisional serious post about something related to my trading or answer a serious question if I think I have something useful to say. This is my contribution. In return, I get to play the rep game (and I am quite good).
Without a doubt, there are members with High rep for low quality posts, and vice versa: check out the Potential Setups thread - these guys talk pretty much exclusively about potential setups and how they are managing their trades... few gold stars there though.
We take from T2W what we want. Witty Banter / opportunity to get on a soap box / self gratification for making good quality trading contributions. Any half-intelligent reder will be able to determine for themselves who makes good trading related posts and who doesn't. Any half-intelligent reader will realise that the rep thing is just a social game played by the regulars.
