1. Twitter and Pinterest are social networks.
Who started this one? For years, Twitter was accurately referred to as a microblogging service. But in the past year or two, suddenly everyone lumps it in with Facebook as a "social network." Pinterest, too.
They're not social networks. Twitter and Pinterest are blogging services in the same category as Tumblr, Blogger and Posterous (acquired by Twitter in March) -- services that let you publish your words, along with links and pictures, to lists of people who follow you. The only fundamental difference between Twitter and Tumblr, for example, is arbitrary limits on the number of characters you can post on Twitter.
Yes, Twitter and Pinterest are "social." But what isn't social these days?
And since everything is "social," we need reasonable criteria for what we mean when we use the phrase "social network," to distinguish actual social networks like Facebook and Google+ from social blog sites, social video sites, social whatever sites.
Some things are and should be defined by the existence of multiple features. For example, a home is defined in part by the existence of facilities for sleeping and eating and bathing and so on. It’s not one of these features, but all of them that makes a home a home.
A bathroom by itself is not a home. A kitchen by itself is not a home. A "home" by definition is a building with multiple basic functions for living.
A "social network" also requires a combination of communications media. Facebook, the quintessential social network, let's people broadcast status updates, post on walls, poke, chat, message, Skype, comment, upload pictures and more. It’s these multiple avenues of interaction that make a social network a social network.
Twitter is just “status updates.” Pinterest is just pictures with captions. As such, they don’t qualify as “social networks.” They can’t be meaningfully categorized with Facebook and Google+.
So let's stop being sloppy with language. Twitter and Pinterest are not social networks.
He holds his own broken tusk in his lower-right hand and holds a delicacy, which he samples with his trunk, in his lower-left hand. The motif of Ganesha turning his trunk sharply to his left to taste a sweet in his lower-left hand is a particularly archaic feature. ... In the standard configuration, Ganesha typically holds an axe or a goad in one upper arm and a noose in the other upper arm....as depicted in my painting, although mine has a lotus, not a noose, which is also common in some depictions of Ganesha.
