As a keen blogger myself, I can only say that Harold is spot on. I've never met Harold but feel I know him now and have learnt a lot from his blog posts and tweets. I also agree with the point about blogging being a personal 'voice'. Organisations don't blog, people blog. Unlike other forms of social media, it allows some depth of analysis. But it's more important than this. In my travels to the middle east last year I saw the power of blogging to affect political change. Believe me these bloggers are brave and effective. Some have died for their cause, others imprisoned and tortured. But it was their amplification and blogging of corruption in Tunisia, Egypt and elsewhere that cascaded eventually on Facebook and then twitter. Blogging matters.
