"could it lead to a 'standardistion' process?"

Perhps you could say more? I'm not exactly sure what it is you're suggesting.. Standardisation of what? Standards on other internet spaces where you have 'virtual singarounds/sessions' so to speak? For me, I think it's great that a pro. folk performer is putting himself 'out there' in a naked fashion. Especially as (IMO) there's nothing more musically exposing, than the unadorned voice.
