Reaction to Business Plan...

So we all wrote our business plans this week.  Personally, I had a blast writing mine!  Even though I may not ever follow through with this idea, it was really fun to write in a way that would make people believe I will.  I was having so much fun I hope I didn't go overboard but I loved writing confident (borderline outlandish bragging) statements regarding my idea.  I did have one question: would a business plan be something to complement a powerpoint presentation, something I would present on or something that the investors get separately, to read at their leisure?  Just trying to further wrap my brain around this new world of business!
