Being in many social media places at the same time ...
The above image is by no means definitive - it does however describe how I link some of my social media inputs to multiple outputs. I am always wary to respond when asked about my impact as the measures are multiple.
In effect I have three inputs (hootsuite, blog and twitter), yet there are eight outputs (blog, google+, twitter, LinkedIN, Facebook, Tumblr, WordPress, Medium). Each has their own affordances, each reaches different communities of interest.
It isn't difficult being in these multiple places, some of the work is accomplished by TwitterFeed - for some it is also done via IFTTT as well as the specific integration resources available on a couple of platforms.
In doing this, I can easily multiply my outputs by virtue of a single input. Something that should make sense for any social media savvy academic.
