It's well documented that Photojojo's Photo Time Capsule is the third best thing on the internet. (The first being Flickr, the second being Words With Friends.) It's very simple; you sign up and twice a month it emails you flickr pictures you took a year ago. It's always such a moment when the emails arrive - instant nostalgia mashed with instant intimations of mortality.
It, for instance, just sent me this:
Which I can't believe is a whole year ago.
Which I can't believe is only a year ago.
Anyway, point being, there's a new brilliant and similar thing in town - twitshift - which lets you do the same thing with your twitter.
You set it up and it sends you your old tweets a year later. Genius. Suddenly you're getting daily reminders of how things were, what you were doing, what you wanted. Sometimes they goad, sometimes they sadden, sometimes they remind, but they're always another interesting atemporal layer.
(Note to anyone looking for a cynical nethaterz angle on this for a column - how self-involved can you get!!?)
(Remember - you need to set up a new private account to do the retwittering at you, otherwise you risk re@ing all those people you @ed a year ago.)
