Yes. You are looking at it from a developer/employee point of view. Running multiple businesses I know for a fact Facebook is a must. Even CEOs and other execs at companies using our products reach out routinely over Facebook. Then of course you have the private groups. So much business is done at private FB groups, you have no idea. Leads that we have been chasing for a long time over regular channels such as email, phone, Linkedin, etc. - became closed deals due to short Facebook messenger exchanges with decision makers.

That's on the business deal making side.

From a consumer point of view - if you don't have presence on Facebook, you simply do not exist.
