In March, we launched Mashable’s Google Wave API Challenge, a month-long competition to create exciting new Google Wave extensions. Now it’s time to vote on the best ones!

To explore, vote, rate and discuss the submissions, visit the Mashable Google Wave API Contest Submissions Wave – there are 24 approved submissions to choose from.

There are 3 voting categories: Most Fun, Most Useful and Best Use of the Embed API. We’ll then pick a Judge’s Choice as the overall winner. The winning developer/development team will receive 2 unlocked Nexus Ones, see their extension featured on Mashable AND receive free passes to the Google I/O conference.

Public voting is open from April 12th to April 19th, 2010, with the winner being announced on April 21st, 2010.
