I certainly felt the hooked effect with Reddit and ultimately other similar sites (HN) where one just aimlessly scrolls and clicks sometimes over and over the same content. The productive hours just wasted. Using a news aggregator with RSS feeds eliminated this for me. I tend to find new content doesn't drip through quickly enough meaning I'm less likely to open the aggregator as there's no "reward". If there is, it'll be a hand full of articles that can quickly be decided on if of interest and no hunting for that kick.
I agree, I also find myself looking through different social networks and seeing the same content repeated.
