I find it is not the number of people that recommend shows to me.
It is who recommends shows. Friends, some colleagues etc.

Basically, if a friend or acquintance recommends a show to me, I’d watch it if a) they have never recommended something to me or b) their previous recommendations were good. Even if they only recommended one show before, if it was good to me, there is a good chance we might have similar tastes (despite the bad stats behind using one sample).
