Google _does_ have competitors with deep pockets. The post mentions being nimble. You don't necessarily have to be more nimble than google -- just the competitors in the market that would do better to buy you than build their own.

But M&A frenzy shouldn't gloss over the need for a way to monetize a product. If you're building a good user base, and have a way to make money, you're in good shape no matter what Google does...

... maybe.
