"When I see a business model with 5 revenue streams, I know they really have 0."

Selling complimentary products and services to overlapping and peripheral market segments is an extremely valid and sustainable strategy (Apple). Using different methods of distribution to attack different market segments with similar products works extremely well (Amazon, Google). Launching additional lines of business to attack unrelated markets using a singular strong brand also has merit (Virgin).
The key really is "don't have a shitty business model" not "don't have multiple revenue streams".
On the other hand, I really appreciate Rob's points about how clever often means convoluted (I am always wary of "complicated") and that mediocrity and a lack of focus can be dilutive.
Are they one business model? Cause they certainly have several different successful products, although i'd claim that they have a single methodology that's applied all of them (hosted web apps that don't require humans to scale up).
Likewise Microsoft... OS manufacturer? Office Suite product company? Video game manufacturer? Web-based something or other?
Ultimately, using Google or any other Fortune 500 company as a model for how you should do business as a fledgling startup is probably not a good idea.
My startup-land rebuttal for this claim would be 37signals: http://37signals.com/svn/posts/1123-theres-more-than-one-way...
Early on, as a developing firm, Google focused on that single revenue stream to great success.
He is clearly talking about clarifying your business model in the early (pre-launch?) days of a startup. In that context everything he says about simplicity and focus should be kind of self-evident.
To crudely paraphrase, if you haven't got one solid good idea (revenue stream, whatever) then 5 bad ones probably won't help you.
I agree for the initial phase of a startup this is a good strategy, but does it really make sense to ignore additional revenue streams which might actually be better than those you originally decided to concentrate on?
Maybe because it was a good way (or a potentially good way) of making money?
Maybe because you wanted to have a foot in the door in what might turn into a full pivot?
The example of Google is a terrible one, because sure they make all their money from advertising, but based on the "You want to focus on the most promising possibility, exclusively, until it’s no longer the most promising possibility" logic, Google shouldn't be doing anything except working on their search engine, not branching off and spending time/money on gmail, maps, plus, etc. etc. etc.
So if you put all 5 revenue sources in a single model, and one of them fails, you can justify continuing testing that business model to yourself because there's always another revenue source to test. (This is compounded quickly by all the possible permutations of value proposition, customer segment, channel, relationship type and engines of growth.)
Whereas, if you have simple models to test, and the single revenue source fails, you can take action on this by crossing off that specific model and moving on to the next one.
Simpler models in this case help you pull out discrete and actionable learning, and to focus on one thing at a time, and move on quickly if the concept doesn't check out.
