I just voted! I tried to be as objective as possible. I had only been to 5/20 of my selections, so it also entailed some research and considering some of the comments by other more experienced members.
In choosing 20 sites, I considered how iconic. outstanding, and what the site would add to the list. I also considered if the values of the property were not already represented on the list.
My assumption is that I had far more than 3 sites in common with you (Els) for our Top 20, no? I am excited to see the results.
I am purposefully not revealing any specific sites I voted for, to have no effect on current voting.
For the final list of 119 sites, there are technically 12 sites from the United States, 9 sites from India, 7 sites from France, and 6 sites from Russia. I wonder if this offers too great a temptation for "national-pride" voting? Hopefully, this does not occur.
