How do I find/make friends for my yahoo 360 page?

You can do a search for people with shared interests in the 360 search feature. I found a couple of good friends that way, by searching for other people who also liked my favourite band. Some people here on Answers have a link to their 360 on their Answers profile page, so if you find some interesting people, you could check out their pages that way. You can then invite them or leave some comments on their page and / or in their blog (if they've made that feature available to public). I've found friends that way too. When you find some interesting people, you can also check out their friends pages as they may have similar interests as well, or you could always invite some people you already know to make a 360 page as well.
