Slackjaw, as you've mentioned my name specifically, I should point out that I reserve the right to change my mind about everything, on a regular basis, for no particular reason.
My trading style and performance has changed dramatically in the 14 months I've been a member of these boards.
If I have in that time failed to contradict myself at least one hundred times, I'm clearly not trying.
If you're into analysing evolutions - I'd personally choose someone with far fewer posts to their name. It'll make your life and your quest, so much easier.
Number of posts is absolutely no direct indication of quality, success, intelligence or experience (except in my case of course) - neither is the converse necessarily untrue.
What's more useful might be to consider who is posting stuff right now that seems to you to make the most sense?
There are outstanding contributors on these boards (and others) who have very low numbers of posts, but are clearly 'on the money'. Their low post rate means they're not immediately 'current; for new members and retrospectively post-mining for them however is so time consuming as to be prohibitive.
It would be useful to be able to sort on members reputations and star ratings, but even that couldn't be guaranteed to throw up all the good stuff as we don't always remember to 'thank' the good posters in this way.
Good luck with your quest and if you do uncover any mental instability evident from your analysis of my progressively demented postings - it's only going to be news to you!
