I hate to sound like some stuffy schoolmarm, but as I have said before (see How important is my business plan?, for example), the purpose of writing a business plan is the writing, not the finished document. I am therefore concerned that you're stuck with the plan: perhaps you're stuck on fully thinking through the business itself?

The harsh reality is that business ideas are a dime a dozen. It's not about the idea. Success comes from implementation, execution, and follow-through, and those are a heck of a lot harder than sitting around dreaming up crazy/cool business ideas.

Further, I know that it's a common tendency for business founders to envision a world-changing, paradigm-shifting future for their business, but if you can't get from point A to point B first, you'll never change anything, let alone get rich in the process. My point? I'd take a deep breath and lose the "dominate" jargon at this stage in development of your business vision: just think about growing quickly and sustainably.

You are also entering a tough economy in terms of raising venture capital or any other money for your startup. You need a strong track record of creating successful businesses from scratch and you need to have some proof of concept that your idea really is the foundation for a successful business.

That's why I always recommend that companies, whenever possible, get a test market or beta or early / limited release going: once you can show that for every $1 you invest your customers bring back $1.30, you have something to go show potential investors who might then be able to pony up the $50k, $500k or millions you need to grow big, fast.

If after all this you're still stuck half-way through your business plan writing, try finding a close associate or friend who is willing to lend you a sympathetic ear, then sit down and explain to them, in detail, exactly what you're trying to do, the SWOT (strengths, weaknesses, opportunities and threats) analysis, and where you're stuck. Often just explaining something will help you get through the blocks.

Please don't take this as any sort of discouragement. I'm a startup zealot myself - I've founded four, so far - and think that the best innovation in the market comes from that wonderful combination of a great idea and a great implementation.

Good luck!
