I posted this a while back, and I think it applies to your attitude.

I'm coming up to 17 years on this site -- it's helped me learn tons of stuff, and helped me out immensely on a professional level. And I hope I've helped a couple of people learn as well.

Instead of immediately calling for a complete site overhaul, take the time to learn about this site, and see what you can do to help. Yes, it might be possible to do a complete rewrite of this site using modern technologies -- but do you have the resources and knowledge to support such a task? I haven't seen proof of either. I'm not saying "Don't do it!" -- go right ahead. We'll continue to watch your progress with interest. :)
