I've started a new blog about tax - partly to be about the avoidance thereof, and partly to be about bits I think are unfair the other way. It occurs to me that I probably ought to tell people about it, though :-)
I've done it entirely separately from LJ - mostly as I think it's going to end up TLDR - but if anyone's interested it's over here:
http://andrewjjackson.wordpress.com/ I may still rant here, of course :-)
