If you really think bakers don't benefit from using computers, then you're just not thinking very hard. I always look up the reviews of the bakeries I go to if I'm buying a cake or something. I wouldn't risk buying something at a bakery without checking online if it's worth it or not.

If websites DIDNT matter, these small businesses would not have websites at all. I'm not saying you need a good website. You just need any website for discovery. Your example actually supports my arguement - why would small businesses be wasting time with websites unless it helped them?
