Very interesting how you are doing this. i was thinking of something similar with one of the healthy food topics - I think I would only put the top 10 maybe - this looks like a huge project.
Do you notify the people that you do this list when you do it? I was thinking I would comment on the posts I include, but that would be too much work with your list.
Great effort - any advice gratefully accepted on how you pull this off. Upvoted :)
