A lot of things have changed since the days of Flickr. Facebook has concentrated the sociality of the Internet within its blue borders, like a Walmart siphoning off the mom-and-pop shops that formerly comprised the Internet's gathering places. Communication, in the age of mobile dominance, has become, of necessity, shorter and snack-sized.
I first got online in the late '80s when I was an eccentric teenager in suburban New Jersey, in a town mostly interested in sports, popularity, and clothes. I was a reader, into Jorge Luis Borges, and I found, connected to, and delighted in a group of Borges scholars from Aarhus, Denmark, that I met online.
The Internet is full of strangers, generous strangers who want to help you for no reason at all. Strangers post poetry and discographies and advice and essays and photos and art and diatribes. None of them are known to you, in the old-fashioned sense. But they give the Internet its life and meaning.
