Mashable and Second Brain would like to announce that the Beta2.0 of Second Brain is launching at the end of May. To celebrate the upcoming launch and reward the growing Second Brain community, we're sponsoring a super cool Second Brain contest for registered users.
Simply register a Second Brain account on or before the launch, add some valuable content, invite some friends and create a great collection of content. The person with the best combination of content, collections and network will get his/her very own spanking new MacBook Air. First and second runners up will be awarded an XBOX 360 console or an iPod Nano respectively. Other runners up will receive $50 gift cards from Amazon.
