Politics: PR? Your Job's In PR?
But any kind of anonymity you wish to keep is pretty much DOA if you sign your real name to your blog. This means you have to be a little careful if you intend to either be political (like Monte Solberg) or decide to call yourself a reporter and do a puff piece on a white supremist group like Stormfront. (No, I'm not linking to Stormfront again.)
One thing to always bear in mind is that whatever you write can be used against your if you're in the public eye. One group that should know this, other than politicians, is someone who calls himself a "public affairs consultant". At least he was a volunteer instead of an official member of the Liberal Party, but that's just being thick, whatever your affiliation...
