We're a YC company (Winter 2011) that helps people get more out of conferences and professional events, by finding the right events to attend, meeting the right people at the event and catching up on slides, notes and video afterwards.
If you sign in to Lanyrd with Twitter we'll suggest events to you based on the people you follow - including events your contacts are speaking at, attending or just tracking through our site. Give us your email address and we'll send you a semi-frequent email with new events your contacts are interested in.
You can also browse the site without signing in at all, or subscribe to our RSS and iCal feeds. Here are some of our lists of upcoming events:
http://lanyrd.com/topics/python/ - 17 upcoming events
http://lanyrd.com/topics/startups/ - 45 upcoming events
http://lanyrd.com/topics/javascript/ - 59 upcoming events
Plus you can browse and search by location, e.g. events in London: http://lanyrd.com/places/london/ or Europe: http://lanyrd.com/places/europe/
Finally, we have mobile apps designed to help you keep up to date with the schedule, speakers and attendees while you're at an event. We recently updated our iPhone app http://lanyrd.com/iphone/ and we're currently working on a new version of our Mobile Web / Android app http://lanyrd.com/mobile/ - both iPhone and Mobile Web apps use offline storage so you can still see the schedule etc even if you're travelling abroad or are on dodgy conference wifi.
I did not know this. Thanks for the reply.
