Just picked this up via the Open Rights Group website. Tom Watson MP has a blog and has solicited opinions on his colleague Andy Burhnam's Big Idea - that voluntary age rating of internet sites is a practical solution to the perceived problem of nasty websites being inflicted on unsuspecting kiddies.
A quick squizz through his blog suggests this blog posting has generated a larger number of comments than any others - mind you, even his worst-commented articles do better than most of mine in that regard :-(
Postscript - some of the comments left at Watson's blog are particularly helpful and informative. Oh, and pretty near universally opposed to Andy's Big Idea.
