AFTER READING ADRIAN WECKLER in the Sunday Business Post (at left) ruminate about the echo chamber he found in Google Plus, I realised his perspective is numbers-based, not diversity-aware. And that's just fine.
It really doesn't matter if a boatload of friends swim alongside your presence inside Google Plus. If you play social networking like an extension of a real-life social circle, you need to extend where you hang out in real life. So if you get info about pub crawls from Foursquare check-ins, stick with that. If the news you use crests on Twitter, don't abandon that. If your family exchanges images you cherish on Facebook, why walk away from something that works? So many valid social networks exist today and each has strengths of purpose. You risk information fatigue if you're a mere joiner.
However, you might find something really interesting if you spend time to poke around and engage with the G+ flow that extends beyond the names and faces you already know in other places.
