What I collect is not substantial, but I guess it could be considered as "collecting" too. It is knowledge about character profiles of people, I never miss out to get to know a bit about someone I meet, and everyone fits more or less into one of the zodiacal signs. Therefore, the more people of a particular sign I meet, the more knowledge about that sign I collect, and the better and sooner I can identify someone whom I see or meet for the first time by his sign.
I guess you can call that "collecting people"
