I was quite impressed with how helpful everyone was and that's how i got to know Eric, actually. He was helping me with my code on my site. Then as we talked more and more the relationship helped us both a great deal.
I can always use a bit of wisdom and I try to pass along anything I can to help the others out there. The webmaster side of the internet is really a nice community.
Like you said most people aren't out there as their primary business. And, I think everyone is just happy to chat about their site and what they've done. I can't do it in everyday life. 'Hey, guess what, I upped my
PR by changing a couple H tags in my code.'
Nobody knows what I'm talking about.
