Nielsen have released their list of the top 100 websites.  The list shows user figures for January 2010 and makes interesting reading.   There are some pretty obvious entries on there such as Google, Facebook & Youtube plus a few less known such as Geeknet & Pornhub!  Take a look and let me know what you think
