After two weeks and over 43,000 nominations the Mashable Open Web Awards 2008 online voting round 1 is now open.

Looking at the names that have been nominated, there’s a good mix of new and underrated companies and applications as well as the usual suspects. For example, it’s nice to see the likes of Kiva in the non-profit category after a year when the micro-lending company really came into the online consciousness.

The first round of online voting for the Mashable awards will run from 9am PST today until 11.59pm PST on Sunday November 30. Once this initial round of votes are in, the final round of voting will begin on Wednesday December 3, with the winners announced on Tuesday December 16.

You can begin casting your vote via the round 1 voting form below.
