Web 2.0 and politicians

First it was Omar Abdulla and now it's Sashi Tharoor.Omar's blog was hugely successful but due to a lot of unfavourable comments made on his blog,he quit the Web.Tharoor is in the face of a controversy over a tweet made on Twitter regarding MP expenditures.The partly is not taking it kindly.Whatever the arguments and counter arguments my interest is in the technical aspects of the whole issue.In fact Tharoor has become one of the ambassadors of the Congress Party in Web 2.0.The Congress has not been very effective in using the net to communicate or campaign.
They have a rarely updated website.The BJP fared far better in this aspect.Now if Tharoor is forced to quit twitter,I think it will also scare away other politicians from using the Web 2.0.It remains to be seen what is Tharoors response to the whole controversy.
