Question

How do virtual groups differ from in -person primary and secondary groups? What qualities do virtual and in-person groups share?

I understand people join primary groups to satisfy their personal needs of belonging and fulfillment. Could the differences here is lack of face to face interaction? smaller group size ?

Secondary group is to achieve specific goals,I could not find any difference.

Qualities: yes virtual groups share their ideas online for others to learn and share. Am I right?

Thank you in advance.
