I know this is rather late but:
I must be the only one here that is this pissed off about this... I happened to like looking to see how many people had more posts than myself. I also liked knowing, not by mere experience, who has been here longer and has more experience with a certain subject.
Now when I see someone say something, I don't know if it's someone that hasn't been here for a long time and changed their nick, or if it's some noob who thinks they know everything. Thus I have to try ALL suggestions, whether lame or not. You tend to trust the suggestions of someone if you know they are more experienced in the field. Would you take a pill someone gave you, and they said "Trust me, I'm a doctor."? Would you believe them, or would you rather know that that person has dedicated a very long amount of time in knowing what they are talking about?
I know that you can click that stupid member post and search back through their posts, but thats just a little to much extra research that is just unnecessary. Not to mention the fact that it can stray you from your original intention. I seriously don't want to read through what so-and-so had to say in the porno topic next door, just to see if that person has experience in the catagory at hand. That also goes for having to click a person's profile to check as well.
I think that there should at least be an option here. Start out the new people with the "members post" link, but we should still have the option to have a post count in the "My Controls" section. It's only fair to those who have lived with it so long.
