This will help find the lowest latency server, but the difference
between a 20ms DNS response and a 40ms response is really marginal. If
you're arguing ping times, you're missing the boat here.

Agreed

Why do you say put ISP's servers back?

To Ed's point, it's the caching you want for you and all your friends :)

If you use some server that is a parent server for a bunch of smaller ISP's or public networks then you are causing that server extra work and slowing it down for all of it's upstrewam requests. The idea is you use the closest DNS server to you to best take advantage of all the caching up stream. However some smaller ISP's are not as proficient at maintaining things so do the best you can with what you have.

Since Google is so successful I would just go ahead and beat the heck out of their stuff.
