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. Here are the nominations for August:

• David Beers at Software Everywhere on the future of the Palm OS and the reasons why Palm would not want to license the upcoming linux version of the OS
• Daniel Taylor at the Mobile Enterprise Weblog on the poor state of usability of mobile apps and services
• Rudy de Waele at m-trends.org on connecting cultures through music
• The Pondering Primate on Google, China and QR codes

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