If you've never come across Sirona Consulting's blog (Sirona Says ) but like a regular good thought provoking post then I can't recommend it strongly enough. A consistent mix of  insight, humour and debate generation - exactly what a blog should be about IMHO. My only trouble is I can't seem to help myself from getting drawn to comment (at length) - and his recent post "Would you recruit someone with a visible tattoo? " got me good.
