As a company/organization, Twitter is dysfunctional. I've had a friend quit from Twitter because all the other smart folks around him were leaving...leaving only the rent-seekers. I'm not saying all the smart folks are gone, but there has been a brain drain and it's been well deserved. Jack Dorsey hasn't done a thing to fix Twitter and yet they keep him on.

A huge number of people still use Yahoo Mail, and some use their photo offering.

It does not put Yahoo's finances in a good shape, though.

If Twitter could slash their expenses drastically, they could be rather profitable. Maybe they could increase their income somehow, too. Likely the same applies to Yahoo, and is equally problematic.

Snapchat?
