Almost everyone is familiar with steam love it or hate it. But its can be sobering to see how much time you have put in your games cumulatively.
Of course if you don't want to count all the hours this website will display your hours and other info in a neat graphical format like this.
I currently have 313 hours (I got my computer in June) and TF2, gmod, New Vegas, and Witcher 2 are all tied for the lead.
EDIT: In some cases it doesn't work, because your account isn't public. If thats the case find your steam id #. To find it google your username http://steamcommunity.com/profiles/76561198037489412(<--this # is the id) copy and paste that into the search and it should work.
