Even Twitter? Can Twitter be declining? Over at the Atlantic‘s Technology Channel I note that my own Twitter conversations are not quite as dynamic as they once were, and speculate about why that might be. I didn’t say this in the post, but I wonder whether it might have something to do with people who enjoy online conversations also enjoying new tools and toys: perhaps we get tired of Twitter not because it has a deficiency, but just because it’s been around a while. I’m not suggesting this in lieu of the explanations I offer there, but in addition to them.
