I know lots of folks who like to have everything they share on one social network (eg Google+) magically appear on all others they use, too (eg Twitter & Facebook).
While I sometimes share identical content out to several networks, I rarely want precisely the same thing going everywhere all the time. In fact, while I love employing Buffer and IFTTT (including using the latter to push content from G+ elsewhere), I rarely like having the same posts (which aren’t links) appear anywhere else.
Why? To ensure I don’t miss some of the conversation or points raised by splitting my attention between, say, Facebook and Google+.
I find that the communities represented on the social networks I use, while overlaps occur, tend to be relatively distinct.
I see this problem occur in communities I belong to, too – such as the BGLUG. There’s a Facebook group, and a Google+ community. When events are scheduled, they get posted both places: which is great for publicity .. but not so much for keeping continuity of community.
Continuity of conversation and interaction is a Big Deal™, in my opinion.
Multiple conversation points are great – but fragmentation of discussion is not so great (eg comments on a blog post + comments on the social network link post of the blog post).
I asked a question about a subset of this problem a few years ago on Stack Overflow – and the best answer for integrating WordPress-to-Facebook commenting was to use a plugin. That’s awesome – but doesn’t begin to solve the problem of discussions across more than one network.
So, for now, I’ll continue to encourage all my socially-network friends, colleagues, family, and readers to keep conversations as separate as possible on the networks they frequent: improve your signal-to-noise ratio, and make the internet a better place.
