I've cut back dramatically on MB because I got a new job that doesn't bore me to death every damn day! I started as a video game content editor three weeks ago.
Now I barely have time to check my personal e-mail address, let alone MB! Maybe after a few months I'll be back full force.
The best part is that instead of eating a sandwich at my desk every day (trolling the internet), my cool Turkish colleagues invite me out for lunch* and we actually hang out. My British/Australian/American colleagues at the last job were so goddamn antisocial I just ate grocery store food by myself every day.
*paid for by my new company
So I'm still checking MB from time to time, but note that the reason I joined was to kill time at my old job.
