I think that it's reasonable to feel conflicted. The internet is interesting and addictive, especially the social corners. Other commenters have pointed out that SA, HN, FB, etc are potent time sinks--it's all too easy to spend more time than you should. Of course, whether a site is a good use of time isn't an all-or-nothing proposition. It can be productive to skim the news for 10 minutes a day. It's a good habit to periodically reflect: would I be happier spending more time there, or would I be happier spending more time [working on that side project, with my family, watching a movie, hiking, etc]. Most highly effective people 'waste' their time too, just that they're aware of the decisions they make, and strike a good balance. It's important not to let play get in the way of work, but work isn't the only thing worth living for.
