Me? I was burnt out from writing a novel and needed some time to get away. I heard about hubpages and decided to drop in and write a Writing 101 series to go over all of the things I had learned about writing over the past 11 years.
I then discovered you could get paid for writing here and went about deciding what things I knew about that others might be interested in and started writing hubs for profit.
From there, I decided to write some hubs explaining how to use hubpages, as I saw many people struggling like I did at first and became determined to help them out.
So, what started as a short getaway has sort of become a new home for me. :)
