Seeking Alpha has an informative graph and some interesting stats on 20 websites with over 20 million unique visitors for the month of October.  The list, in order, is as follows:

1. yahoo.com
2. google.com
3. aol.com
4. msn.com
5. ebay.com
6. live.com
7. myspace.com
8. mapquest.com
9. microsoft.com
10. amazon.com
11. wikipedia.org
12. about.com
13. go.com
14. ask.com
15. youtube.com
16. walmart.com
17. passport.net
18. adobe.com
19. geocities.com
20. target.com

The report, which originally appeared on the Compete Blog, also has some interesting stats comparing the stats to those of a year ago.  Of particular interest to me was the fact that paypal.com and weather.com both fell out of the Top 20, even though their traffic was up over October '05.  Could this be a sign that overall internet traffic is way up?  What do you think?

The graphs are certainly worth a look.  They illustrate visually the huge difference in traffic between the top 3 and the remaining 17.
