As a Digital Strategist and owner of getCONNECTiD Digital Marketing Company I get asked regularly what social networks I and currently using and how.

So here they are. My social networks of choice

Facebook – I am on here every single day. The leverage of engagement is HUGE.
Twitter – I am part conversation firestarter + part listener + part master retweeter.
Instagram– I use this alot. Did I say alot!
LinkedIn – I’ve gotten better at this.  Your NetWork + Leverage in business is everything.
FourSquare – I use this alot when travelling for search and discovery.
Quora– I barely use this, though I think I should be there more.
Google+ – I am not there alot but it gives lots of Google Search Juice.
Klout – I like to see my score every now and again
