I had never talked about Populicious, a tool that makes web rankings based on the favourites webs of Del.icio.us. It?s very interesting. But the fact that it was created by a Spanish man, Xabi Vázquez, makes it even more appealing.This tool (that only includes data from February 2005 at the moment) will gather more information as it develops and it will be able to offer very valuable data. Although it runs the risk that Yahoo, new Del.icio.us owner, would take this job up.The quality of the results will improve as the users of this tool stop being geeks. Then, instead of finding Ajax manuals, we?ll surely find recipes, something much more delicious.
