It's all about balance. Learning about various stuff from well written articles and Wikipedia for one hour is good. Doing the same thing for the whole weekend isn't.

Even reading books all the time to the detriment of other activities isn't good.

What's good is doing a bit of everything. Reading a book an hour before sleep, doing a hour of exercise two to three times a week. Reading a few blog articles, wikipedia, long and well researched magazine articles. Making time for in person social interactions. Playing games, video games, board games, card games from time to time. Engaging in a few online discussions every week. Etc

It's all about balance or at least that's the way I see it.
