I use google suggest to get new post ideas, I start out by typing “what is”, “who is”, “how to”, “when is”, “where is”, “excel” and see all the suggestions Google comes up with. If I see something interesting I would mark the search topic and use it for posting here. And for the last few days I have been seeing that when I try “who is”, the search query “who is (Barack) Obama?” is popping up. Either he is really unknown (unlikely) or provoking curiosity in many people.
Ok, time for sharing another set of juicy excel posts around the web:
