Does Professional Networking needs a makeover?

Experiences collated by interacting with a community of professionals.Please suggest if there is anything more to be added.

Virtual Networking a)Building connections with un-inteded purpose.You don't get a chance to express WHY (why you wanna connect)

b)2.Replying on virtual introductions = Time consuming + Depending on someone else.

Offline Networking A)Events/Meetups surround you with thousands of people.How do you build connections ? (wandering through name tags??)

Realisation: Professional Networking needs to Engage + Evolving + Long lasting
