Add To Any Launches Personalized Smart Menus

Add To Any is announcing an update to their service that could help publishers get more viral distribution. With today's update, users who click the Add To Any button on a Web site or blog will have their favorite and most visited services appear first in the list. Named "smart menus", the personalized menus require no user involvement. They pick up the visited sites from the user and show those first in the list. They describe the technology as, "Behind the scenes, the widgets process a predefined link list of all services, and determine which services have been visited via a special property that browsers give to visited links.  This works in all modern browsers and is near-instantaneous."

For users of less popular services, the smart menu launch will mean that it's more likely a user will use the Add To Any menus more than in the past.

Add To Any's business model is simple: paid service inclusion. Services pay a fee to appear in the Add To Any listing. I wonder what today's announcement will do to their business model. For example, do paid service still appear first or will my recommended services always be forced to the top of the list?
