I have given this some thought and changed my mind

Good man! Good on you!

I believe we do need music critics,but if they are to be taken seriously,the standard of reviewing must be high

Absolutely. Like any other endeavour that is placed into a public arena, reviewing needs to be of good quality with no room for sloppiness or laziness.

I also feel that a site where reviewers reviews could be reviewed would be a good thing

Ah... who watches the watchmen? Might be a bit boring though!
