Thanks for the shout out Khürt. I think that we just need to be realistic about what we can achieve and what we actually "need". Do we really need to be on all networks following everyone? Do we need to follow every blog?

What I try to do is tailor my social experience to the service in hand and thus divide up my following between them. If I subscribe to a blog via RSS do I need to follow the associated social account if it only publishes the same posts? If someone spends 90% of their time on Twitter do I need to also follow them on Plus if there is no real benefit? Why duplicate.

Sometimes there is no option and people use multiple networks effectively tailoring their content to each one so you end up following them in multiple places but I think we all need to step back and think hard about exactly what we want from social then not be afraid to "miss out" on some of the other bits.
