Tile style seems to really de-emphasize the titles of the articles in favor of their score.

Emphasizing the score, especially with the ranking algorithm being so time based is fairly confusing. It seems like the number should be in order, but they of course aren't.

A fix may be as simple as changing the two greys, having the darker grey behind the article title, and the lighter one behind the number. Also, increasing the contrast in the title text would be great.
