>you do get better service over time.

Awesome, now you're stuck in a bubble where serendipity will no longer play a role in you stumbling upon interesting videos you NEVER thought you'd like, same for restaurants, websites and who nows what more?

On a more serious note, I'd argue that you do not get a better service, your profile becomes near to perfect and your experience online, and increasingly offline, will stagnate.
