Every time I hear of a movement to “throw the bums” out, it usually means throwing the other bums out but leave my bum alone. (The double entendre is not lost on me.)
It also appears that conservative bums are thrown out much quicker than liberal bums. I believe we are witnessing that in this election, but it is too soon to tell.
Most of us hate being interrupted. I have learned to freeze my thought and not return to the subject unless the listener asks me to. If they do not ask then they were not interested in what you had to say anyway. Stephen Covery accurately noted that most people listen with the express purpose to reply, not to understand.
I find it rude if it happens a lot, and avoid further contacts with such folks.
On the other side, get to the point. Most of the time an introduction to a point is not needed.
Writing serves to both clarify and expand. It is interesting how many times I start with one point and mutate to another.
While the blogosphere has a long tail and allows one to explore an idea with some depth, it removes the discipline of editing content that the print medium requires. There is a tendency to write to what is trending rather than to take a new course.
