Only highlighting the last two posts, without dates, is a disservice to readers - particularly new visitors - who want to get a better idea of what topics the site covers and how often it does so. Tack on the fact that ALA is one of the only sites I visit sporadically because I know it will be relevant and now I'm lost trying to figure out where I'm at and where I should go. A content site should highlight the content, not hide it. Do they publish a certain amount of articles per timeframe, or is it random? If it's random, now the design is playing favors to posts who aren't up as long as the others.
