These are listed under "my traffic sources" in the box on the left of my account page.
I see referrals from 6 of what I guess are search engines: search.yahoo.com, bing.com, ask.com, search.aol.com, search.mywebsearch,com, isearch.avg.com, plus Google from 14 different countries.
There are places like facebook and a few individual's addresses - not sure why some people's addresses show up but sometimes they do, and hubpages. Plus people who come in through my profile page. I've given that address out because it's easy for friends and relatives to remember.
I've clicked on the different referrals out of curiosity and been taken to various search engines, so I guess that's what they are.
