Check this out! With no advertising but word of mouth and an extremely rapid and viral spread in the odd world of livejournals ... this initiative by the Young Dems of AZ has already brought in over 600 youth vote pledges from around the country in just over 48 hours WITH NO ADVERTISING.
The official kickoff for this is today at ASU in Tempe -- I'll write about it later if it ends up being good.
Really cool stuff. If you are "young" or know somebody who is - get them to take the pledge.
