No, it isn’t a Happy Cog project (it’s by Simon Willison and Natalie Downe) but we couldn’t love Lanyrd, the social conference directory any more if we’d created it ourselves.
Lanyrd uses Twitter to tell you which conferences, workshops and such your friends are attending or speaking at. You can add and track events, and soon you’ll be able to export your events as iCal or into your Google calendar (the site is powered by microformats). Soon, too, you’ll be able to add sessions, slides, and videos.
The site’s not for everyone. It’s for people who attend web/UX conferences, and as it was created by inhabitants of the UK, it presently focuses mainly on Western European and North American events, but that will change as more people use it.
Congratulations and thank you, Natalie and Simon.
