Usual stuff about RTs don't necessarily mean I agree. I will RT stuff I vehemently disagree with as well as agree with. I welcome my opinions to be challenged respectfully but abuse will not be tolerated.
@CleansedTweets I use it all the time, mostly as a term of affection for friends.
Also, I became very good friends with a woman I used to work with because of our shared love of the word. We don't work together anymore but are still good friends.
