>Is there any thought to having a que where sites are reviewed in the order that they are submitted?
Yes. It's generally rejected, because of the enormous problems it would cause.
>Seems like this would be the fair way to treat websites and eliminate any favoritism.
No, no, a thousand tims NO!
The fair way is to treat websites that AREN'T SUBMITTED AT ALL just as well as the ones that are.
And to totally ignore when, whether, or by whom a website is submitted. What, after all, does it matter who submits it, or when? If the website is up, it has just as much right to a website that has been submitted a thousand times: if it's not up, the fact that it's been submitted dozens of times already gives it no credence whatsoever.
You're thinking altogether too much about being fair to SERP perps, and wasting no time at all thinking about being generous to surfers. We're all about the latter.
Your time you can give away to anyone you want. But you must allow other humans the same privilege!
