Great article Bill. I think even before identifying overused strengths, it's a good idea to go through the list you gave. There are many strengths there that can become weaknesses. Empathy is an example. It's generally good to have this trait but misused or used indiscriminately can result in being taken advantage of and not appreciated. So it becomes a weakness. It's a really good exercise to do, as misusing strengths a lot can look like someone has a lot of weaknesses - until they identify them as strengths.
