Dale,
I don't understand why your answer should deserve downvotes, although I'm not inclined to give it an upvote either. It is a simple - and very good - description of how you choose to do your work here. Some people may write long flowing descriptions of a person's life, with not too much empasis on the essential timeline facts, while others may emphasize pretty formatting with all kinds of graphics (flowery borders, wallpaper, lots of pictures, etc.) Some people may find it convenient to add 1 person and work on every part of the profile to complete it before adding the next person, while others may add a person, get 1 (or more) sources entered, then move on to the next, plannig to make a second pass at all of them to flesh out the narrative.
I have (fairly recently) learned the importance of categories. They effectively provide another way to search. If you want to know who lived in a particular place, you can go to the category page for the place and easily find all the proflles ... provided, of course, that the categories for where someone lived have been entered on profiles of people who lived in that place. This is why it is very good to have categories - as many as appropriate - on profiles. Is it the most important thing to put on profiles? ... certainly not, but at some step in the profile building process, it should be done. This is not "fluff" - it is a very useful research tool.
