I guess this post could be summarized as:

The Restaurant: your website is the final destination

The Taxi: your website is the means of getting there

There are thousands of restaurants, but not many taxi companies. The more lucrative business is the taxi company.

Maybe he's on to something. This post reminds me of the old New York joke:

"Why doesn't your restaurant have a parking lot?"

"If I had a parking lot, I wouldn't need a restaurant."

A funny metaphore. But if you think it to the end: I would rather open a restaurant than being a taxi driver, because it's much more fun, there's more creative work to do, you have more liberty in your decisions, contact to your customers is closer, competition is not around price but around quality.

some things are easier said than done
