It's still a question which form is more descriptive to a surfer, but many webmasters cite a trend that thumbs are much more productive, and simplify searching. On the other hand, LinkLists have a larger amount of unique text, so that helps them to improve their positions in search engine listings. TopLists are linklists whose internal ranking of freesites is based on incoming traffic from those freesites, except that freesites designed for TopLists have many more galleries.
