Keeping track of your consumption ◉_◉

I started tracking my movies and series on moviepilot.de. They added gamespilot.de and I started tracking games as well. ◉◉
As I began watching more animes I started tracking them and my mangas on myanimelist.de. ◉◉
A friend recommended trackt.tv, so why shouldn't I sign up and track my movies and series on this site and the app SeriesGuide as well? ◉◉
What is fun tracking, too? Achievements... http://astats.astats.nl/astats/ ... oh and music: http://last.fm/ ◉◉
A big gab opend in my heart because a big part of my consumption isn't still detected by any side: books! ... http://goodreads.com/ ◉_◉
