When I see that one of my posts has been retweeted, instead of a “Thanks for the RT!” I often like to reciprocate with an RT of my own. This is often as simple as clicking the user’s profile, reading her tweets, and selecting an appropriate post to RT.
Easier said than done. Lately I have been having a harder time finding a tweet that I am comfortable sharing with my followers. Understanding that a retweet is an implied endorsement of the content and author, I am cautious about what I share.
