Margaret Atwood is one of the most popular authors who’s an active user of Twitter. In this fantastic New York Review of Books post, she muses on Twitter’s personality and her evolution as a Twitterer:

[O]n Twitter you find yourself doing all sorts of things you wouldn’t otherwise do. And once you’ve entered the Enchanted E-Forest, lured in there by cute bunnies and playful kittens, you can find yourself wandering around in it for quite some time. You might even find yourself climbing the odd tree—the very odd tree—or taking refuge in the odd hollow log—the very odd hollow log—because cute bunnies and playful kittens are not the only things alive in the mirkwoods of the Web. Or the webs of the mirkwoods. Paths can get tangled there. Plots can get thickened. Games are afoot.

On Margaret Atwood’s early days on Twitter:

When I first started Twittering, back in 2009—you can read about my early adventures in a NYRblog post I wrote two years ago—I was, you might say, merely capering on the flower-bestrewn fringes of the Twitterwoods. All was jollity, with many a pleasantry being exchanged. True, some of those doing the exchanges represented themselves in masks, or as pairs of feet, or as rubber ducks, or as onions, or as dogs—quite a few dogs. But having had an early career in puppetry and a somewhat later phase during which I amused small children by giving voices to the salt and pepper shakers, I was aware of the fact that anything can talk if you want it to. My Twitter friends were not only sportive but helpful, informing me about Twitpic, letting me in on the secrets of acronyms such as “LMAO,” analyzing the etymology and deep symbolic meaning of “squee,” and teaching me to make many an emoticon, such as the vampire face, represented thus: >:>} (Though other vampire-face options are available.) They led me to extra-Twitter adventures: a live chat on DeviantArt, a website where I found the cover for my book, In Other Worlds: SF and the Human Imagination. To this day I rely on my Twitter followers for arcane information, most recently some updates on the vernacular speech of the young. Who knew that “sick” is the new “awesome,” and that “epic” is the rightful substitute for “amazing?” Twitter knew.

As I like to say: Twitter is what you make of it.
