It'd be a useful discipline for me to log and write about the books I read. A blog might help in that discipline and -who knows?- may be useful to ... you?
Maggi Dawn recommends this to her students for the purpose of helping them to make their rwriting clearer, I imagine it helps qy=uite a bit. Not only does one learn a lot of stuff about punctuation but it is actually done in a light-hearted and well-written way that often illustrates the points rather well. I would also put it in the hands of those with orthographic issues.
There is also little comfort in her for those with knee-jerk reactionary tendencies; while good puncuation is the aim, it is clearly kept in view that clarity of expression is the prime purpose of it all. So no rules for the sake of rules.
Despite the tone of the title, Truss is actually quite sensible about issues of linguistic and orthographic change, only betrayed by comments in the last chapter that show that she really would like not to have to be quite so reasonable about it. But then that's her "inner stickler" speaking, I guess.
Brackets: I think these really need reviewing. I generally use square brackets because they don't require the shift key whereas () do and so it seems to me an ergonomic approach favours the square brackets for common use and other kinds for specialised use. So Ms Truss; fro me part of the evolution is to take keyboarding seriously.
