Looking for your input on social media

Hi

Given that we're a motley lot of global souls :) I would really like to have your quick input on this:

In the context of living in foreign places and travelling for leisure or business, could you please list some features of social networks that you would love to get but can't anywhere - or if you can they're too fragmented, require too much management, generally are a pain in the butt.

Many thanks
