Political Connections - The Politician's Viewpoint

A politician friend, who does not wish to be named, said the following in response to my blog posted yesterday:

The problem with political networking on line for politicians is its public nature. It is very easy to forget that your words can be read - and misquoted - when you are on your own with the computer. I suppose this is why so few politicians blog, and those that do often produce a tedious diatribe consisting of their daily engagements and toeing the party line. Left wingers also don't blog to the same extent as Conservatives because online humour can be quite abrasive, which leads to political incorrectness. They find themselves offending their friends and having to apologise. That's why I suspect the Labour initiative you mention will fail in the longer term.

Given the comments that he raises here, what future can there be for politicians getting involved in Social Networks?
