Managing your social media activities

If like me you have multiple social media 'presences' for both work and professional aims, it can make sense to have a policy of what to use and when.

Otherwise, we can end up spending all our time doing nothing else. A fellow twitterer discovered this example from Neal Wiser and I think it makes pretty good sense for anyone who is managing multiple sites or contact lists.

Does anyone else have any ideas on how to manage these activities effectively?
