There is a Twitter App called "Support #IranElection" which lets you turn your twitter avatar green to show your support of the protesters in Iran. All you have to do is log into Twitter using their special link, and BAM, your avatar turns green.
I can't say I know a lot about what's going on in Iran -- I know there are two groups of people, one slightly less conservative than the other, but that both groups are really conservative. I heard the alternatives described as either North Korea (totalitarian with no Western access) or China (totalitarian with some Western access).
There are questions about the validity of the election, but it's hard to say if it was rigged or not. There are questions about how the protesters have been treated, but it's hard to say who's causing the disruptions.
There are a lot of questions, and not a lot of answers, but there is this App that lets you show support for the less totalitarian crowd with one click.
As I cruise around the Internet I'm seeing a lot of green pictures, but I have to wonder if the people supporting the Iran Election protests are doing so because they have a deep belief that the protesters are right and the government is wrong, or if it's a fashionable thing to do.
I think expressing your opinions and beliefs is a good idea (otherwise I wouldn't have posted this), but I think they should be YOUR opinions and beliefs. My fear about these kinds of quick "me-too" apps is that it dilutes the message and can derail a campaign, and ultimately distract people from really learning about an issue because they've already "joined the cause" in one click.
Of course, when we run campaigns at Conquent, we want to see the numbers swell, and remove as many obstacles between a person and their ability to show support. I think the trick in the long run is to find ways to engage those people beyond just a ribbon or a color -- engage, teach, and spread a message with a credible, educated following.
