Because NC just isn't a clean state to play in where you can narrow it down to less than 10 numbers on a consistent basis. It's as simple as that.
Is there information overload - a bit. But - here's a whopper of an idea - try posting your numbers or workout as well, and maybe, just maybe, between everyone that posts, we can FILTER down to those 10 or fewer golden numbers you so crave.
I've never viewed LP as a place for someone else to do all the work and then a non-contributing person can come along and play those numbers. Those who post have spent time developing and refining their playstyles. You aren't seeing what happens after they post - because I can almost guarantee you that they're filtering down from the 30-36 numbers (or however many they post) on their own based on their own intuition or other styles.
I'm not trying to put words into Todd's mouth about what his intention is with the forums, but I'll be willing to bet that he never intended for the threads to be a place where you HAVE to post no more than 10 winning numbers. I'd bet his intention was with each state to post various tips, tricks, and methodologies to develop your own personalized style of play for the individual game because one size does not fit all.
We've had this discussion at least once a month in the year and change I've been a member on LP. The argument never changes - just the primary parties.
Yes, I'm on a bit of a rant - but as you so eloquently started the rant, I'm entitled to voice my opinion in return.
