To me, Twitter is another annoyingly-overpopular lite-content attention sink to create another password to remember for, to learn how it works, and to have my activity tracked and cross-referenced and sold by the “we sell your information” industry.
I’ve never had a Twitter account, but I have occasionally followed links to Twitter pages when someone has pointed out the cream of the crop – usually a kitten video.
I don’t know that the world will be ultimately better without Twitter, but I will smile when I hear it is no more, and hold out hope that it won’t be replaced by something even more annoying.
