Alexa says : yahoo,google, myspace,msn,ebay,Facebook etc... emails first, then e-com sites and Social Networks .
Here is one list of popular websites: http://technorati.com/pop/blogs/ (also see http://technorati.com/pop/ for popular searches etc.) Here you can find popular websites according to Alexa: http://www.alexa.com/site/ds/top_sites?cc=US&ts_mode=country&lang=none (please notice that you can check popular sites from different countries as well from here). While Alexa isn't the most accurate ranking system on the planet, you can still get an idea which sites are popular). You might also want to check out websites such as http://www.43things.com/ to see "what people want to do". By simply refreshing the page a few times you can see that people want to "stop procrastinating", "get married", "get a tattoo" etc.
