15 amazing Web apps built in 48 hours
Earlier this month, the Rails Rumble 2008 announced the eight winners of its programming competition where teams of up to four people had 48 hours to build original (and somewhat complete) Web apps. Ruby on Rails is perhaps best known as the app development platform that built Twitter. But competitions like the Rumble prove how powerful the young platform can be. Here, we showcase the competition winners along with other cool apps of enterprise appeal from the 130 qualifying entries. Winners were selected by an open vote on the Internet and were judged on appearance, completeness, innovation and usefulness.
