As part of its sponsorship of the Carnival of the Mobilists, Khosla Ventures is awarding $250 to the author of the best post each month. Every week, the host picks their favorite submission, and at the end of the month, they’ll go up for public vote. So without further ado, the nominations for June:

• June 2: Darla Mack nominated C. Enrique Ortiz’ post on the mobile perimeter
• June 9: Rafe Blandford at All About Symbian nominated Michael Mace’s post at Mobile Opportunity on trouble with a 3G phone
• June 15: Mobhappy nominated Martin Sauter’s post on incorporating geotagging into mobile applications
• June 23: Rudy de Waele at m-trends.org nominated Stephanie Rieger’s post on “Casual mobile snacks for everyone”
• June 30: Wireless World Forum nominated Ian Wood’s on Just Where Did You Get My Number?

So here’s the poll. To vote, you’ll need to enter the password mobilists.
