Online creatures and their mean ecosystems

As I read the article – Gmail users tweet twice as much – I remember that a couple of months ago someone said during a nice girlie lunch: If a guy gives me a Hotmail email address I’ll probably lose interest, – which was followed by supportive nods of agreement. I learned that Gmail is to be expected. Yahoo might be tolerated.
Wow, talk about strict standards. I agree that Hotmail as a brand doesn’t add points to anyone’s cool factor, but then I wouldn’t go as far as shipping them to social Siberia.

But wait, I forgot to mention that my friends and I are a generation apart – and it shows. Whilst most of my social ecosystem grew under zero influence of the internet and is therefore agnostic to online social codes, to my friends there is no such clear line. Their online and offline personas are bundled together, and increasingly their cultural codes, references, brand preferences (and prejudices) are generated online.

Fair enough, my girlie lunch friends and I all work in the internet industry and thus are fickle early adopters. But from the research we do I get the impression that this is getting more widespread. What do you think?
