There’s no such thing as “better than” or “worse than” when comparing social media platforms.
Each one serves different purposes and is more effective at certain things. Each one has different impact and influence in different areas.
But certainly, there are points of comparison worth considering in evaluating daily time spent on social media. There are only so many minutes in an hour, and only so much time saved by social media aggregator tools like HootSuite, CoTweet and TweetDeck.
