Slackers need not apply

[Paralytic]

Interesting idea, though some of life's introverts standing at the front may be uncomfortable for them. My experience is that good PMs make good SMs.

SM's should not be "standing at the front". The daily standup is not for the team to report progress to the SM; that happening is an anti-pattern.

My experience is good PMs can make good SMs, if they appreciate they are different roles and act as a servant-leader. Bad PMs always make bad SMs as they don't realise they are different roles and don't want to lose the control being PM allows them to have.

This 100%. The Scrum Master is a role, not a person, and a highly performing and mature agile team can have one the team perform the role, with their capacity for feature development reduced appropriately.

When do you know you are talking to an extrovert software developer?

he looks at YOUR shoes

By all means rotate your team into the SM role if you want but first teach the scrum to behave, then respect the temp SM's ability and support them.

The team should be updating everyone in a collaborative way, however that is frequently not what happens.
