Got an email from the lib dems suggesting that I go digg something. What does anyone think about this? It seems like going and voting things up on aggregators is going to be a new form of spam (spag, anyone?) because loads of special-interest groups are going to try it on - and special-interest bodies are going to have a lot of mindless clickers, whereas the rest of everyone has less of a stake in ruthlessly voting things down. This could lead to the ruin of aggregators by diluting their usefulness. At the very least it seems that the aggregator sites will have to fight back against spag, provoking another arms race.
