Workaround:

Description: In ch01s01, we introduce two Kafka modes: Pub/sub and streams. However, it seems like the pub/sub mode might mistakenly lead readers to think Kafka actually pushes messages to consumers in the pub/sub mode.

We should re-word the distinction.

In addition, we should emphasize the differences between the two modes, and include information when a reader should use which mode.

Original feedback by Liam Clarke-Hutchinson on Slack:

Kafka describes itself as pub/sub, but records aren't sent/pushed to consumers, which is key to Kafka's capacity to scale. Consumers can also join the stream at any time and read from any part of the stream.

I note that in the quiz here, that the pub sub model is defined again 
without the usage of the word sent, which is a better way to describe 
it.
