I did the 'limited' third person point of view in my first two novels. However I kept changing who's head we were inside with each chapter, giving a nice build up and differing points of view. So in the new novel I'm working on "The Vampyre Blogs - Coming Home" I wanted to try 1st person perspective, but still do multiple points of view. So, with my wife's advice, I chose the same method Bram Stoker used to write "Dracula". He did 1st person from many different points of view by using letters, journal entries, diaries, etc. and it worked.
In my case, I went for blog and e-journal entries to tell my story, as well as some newspaper clippings to help supply background information for the reader. Now, I know I've said all this before, but I wanted to repeat it for the benefit of anyone who had missed those earlier entries. What I did not count on was dealing with Present Tense vs. Past Tense in the First Person.
This of course gave me a much larger task of rewriting the 2nd draft.
