OK, let's try again identi.ca after a long time... how do I find interesting people to follow?
You could start by checking out this basic user guide for Pump.io.
One of the things you'll find there, is a link to this list of some users, grouped by language, which has links to other means of looking for people.
EDIT: oh, and you could also follow whoever follows you. It usually helps =)
