I probably won't quit watching anime altogether but, I have lost 99% of the zeal I had a few years back. I just can't bring myself to search through a ton of junk (in my eyes) that the industry throws out every season to find the one show I like. AS is the sole reason I saw Shin Sekai Yori and Chihayafuru last year. And, I noticed Shin Sekai Yori only because it got its own sub-forum and the discussions included some posters who had similar taste in anime.
The only show/OVA I'm currently watching is Ghost in the Shell : ARISE and that's because I love GitS : SAC. So, it was a safe bet. I have literally seen less than 10 shows in the past one and a half year, half of which were old shows like GTO, NANA etc. So, I'm as close to quitting as I will get in this lifetime
