Some suggestions:

Follow people. Join in on conversations. Ask questions. Introduce yourself with a post telling something about yourself, and using the Hashtag of #introduction. Look for Hashtags in #cosogroups related to your interests. Change your AVI from an egg to a pic that you like. Page 5 of the guide tells you how to do that. Enjoy the site!
