But on the other hand, you did accept VC funding for Posterous (I'm assuming nobody was holding a gun to your head and forced you to do it), and for whatever reason you then left and moved onto other projects.
Now you are saying you will never sell out, will never lose focus and will stick around forever. Isn't that like a politician promising they won't ever raise taxes? "Ever" is just a really strong word. Life happens. Priorities change. Heck, most marriages don't even last forever.
