100 Hubs on Shakespeare just to have 100 Hubs is wack.
100 Hubs in a month is impossible for real people to do by themselves, if the Hubs are to be even marginally good -- that is, if they are to be somewhat informative and/or entertaining -- and to be Google AdSense magnets.
Unless you are writing just for ego-boo, you have to research and target keywords to get traffic and clicks. If you are writing to make some money, finding a money idea and figuring out what to write about it takes much more time than just transcribing a memory dump about whatever occurs to you at the moment.
Those few that I know of that got 100 real Hubs in a month, not just stream of consciousness mind vomit -- they did the keyword research, then HIRED OUT most of the writing, specifying to the writers hired the subject, the number of words, keywords to include, etc. Then they did a little final editing and posted them.
