I've also heard lack of porn a complaint. But really you got to diversify your jerkin anyway. I think people have gotten so used to the tailored curated subreddits and tumblrs some people have forgotten how to forage for porn.
Well of course I still use Reddit for that.
It's like my bank keeps telling me, gotta diversify.
But yeah, I don't get why it has to be an all or nothing. I read through the handful of things I care to look at on Reddit about halfway through the day unless I'm super busy and dont get lunch or something.
