3 recent pieces about social media

Some excerpts:
"The platforms of social media are built around weak ties. Twitter is a way of following (or being followed by) people you may never have met. Facebook is a tool for efficiently managing your acquaintances, for keeping up with the people you would not otherwise be able to stay in touch with. That’s why you can have a thousand “friends” on Facebook, as you never could in real life."

"Facebook fans aren't much of a guide to anything, since you can become one and then forget about it entirely. Tweets are slightly better, as they indicate how many people are aware of an event while it's going on. But they indicate only awareness, not support."

"やりたくて始めたはずなのですが、この手のコミュニケーションサイトはしばらくやっていると、だんだん疲れてくる……というか面倒くさいと感じてくる人がいますワン。だんだんログイン回数が減り、SNSでの活動がにぶくなった状態を「SNS疲れ」と呼びます。"
