If you’re thinking of coming to the 2008 edition of Where 2.0 in May, now’s the time to sign up. Early registration–your chance to save up to $300–ends this week. Program chair Brady Forrest has once again put together a stimulating, wide-ranging program, bringing in speakers from all over the world to discuss location issues and applications in gaming, activism, green efforts, search engines, history, crowd behavior, and much more. New this year also is a full day of tutorials.
