Votojournalism
The excellent portmanteau of Voter and Photojournalism, for voter-generated content where users post pictures of the candidates on the campaign trail, online. I think the term will be hijacked to come to mean the use of social media by voters, or by candidates (see below) to run an effective campaign.

Microblogging
I was suprised to find that Barack Obama microblogs (blogs constantly from a computer of mobile device, usually one-liners of his movements) on Twitter, and does a really handy job. In fact, he has raised over 40% of his funding online! Funding is key to success in US politics, and Barack’s online strategists have been on the money.

I feel this would have an impact on business, after the elections. You could never bring microblogging to business, but it would be excellent for wannabe celebrities to grow an active stalking community.

Update: this was fleshed out into an article for BizCommunity. Read/Write Web has some interesting stuff on this, although they seem to be looking at the metrics of voting at first blush:  a lot of users in the world deperately want/need the US to change its policies and are following the campaigns, or lending their online presences to candidates they hope will bring about meaningful change.
