I have a number of audiences, therefore a number of different platforms.
HubPages used to be my most prolific source, but things have changed overall which prevents my doing as much writing as recently.
I write for Facebook - under my name and under my business name, "Tilden Editing" - and for LinkedIn under my business name.
I am also trying to keep up with four blogs on WordPress - "Tilden Editing Services", "The Arts Spot", "Wayne's Words to the Wise", and a couple more.
I think, though, that I would prefer to continue my Blogs on WordPress; partially because there is more freedom and choice to the appearance of the final page. This suits my artistic eye better than HubPages.
