Había tres que aún se encuentran en el Explore y dos que han sido eliminadas. Pero fué posible recuperarlas para crear el poster que se ve abajo de este comentario.
Es curioso. De todas esas, 4 son fotos que tomé a amigos. Sólo la que tomé en el Palazzo Carignano pudiera considerarse como "arte", creo.
Aunque Flickr no revela su algoritmo, creo que definitivamente deberian seguir trabajando en él. ;-)
Cito:
Interestingness is
what Flickr calls the criteria used for selecting which photos are shown in
Explore. All photos are given an Interestingness "score" that can also be used
to sort any image search on Flickr. The top 500 photos ranked by Interestingness
are shown in Explore. Interestingness rankings are calculated automatically by a
secret computer algorithm. The algorithm is often referred to by name as the
Interestingness algorithm. Although the algorithm is secret, Flickr has stated
that many factors go into calculating Interestingness including: a photo's tags,
how many groups the photo is in, views, favorites, where click-throughs are
coming from, who comments on a photo and when, and more. The velocity of any of
those components is a key factor. For example, getting 20 comments in an hour
counts much higher than getting 20 comments in a week.
