The auto-retweet button on Twitter could be killing the very thing that Twitter is known for — commentary and an open interchange of ideas.
Back in the day, we used to have to use our copying ability to retweet. See an interesting post, copy it, give credit and retweet. Often there was some semi-tedious micro-editing. (Squeeze the tweet into 140 characters without changing the original tweet TOO MUCH and give credit where it was due.) But often you had room to post little commentary of your own, even if it was just an LOL.
Human nature being what it is, today’s retweet is more frequently being made by using the automatic retweet. Let’s face it — it’s easy and most of us are inherently lazy. Call it the “guess what I think of this one” retweet. It is delivered free of any commentary or context. Love the post or hate it, if I use the official Twitter retweet button, it looks the same. So don’t assume that a retweet means the retweeter loves the post, or even agrees with the post — they may just be pointing out a really dumb comment. Or one that they vehemently disagree with.
