To err is to human. Nobody is perfect. Don't tell me you don't make a single grammatical or spelling mistake. If you're going to criticise my comments on grammar, at least get your own right. To err either 'is to be' or just 'is', not 'is to'. Fair point, yes I could send in corrections (and for the purposes of this response I'll ignore your own mistakes above), but as a reader that's not my job. It's a little like saying J.K. Rowling doesn't need to bother about grammar in her Harry Potter books because the readers can just write back with corrections. :P In my opinion the corrections should be made before 'going to press', especially given many of the errors in this week's articles would be easy to fix. The only reason I comment on errors is because I feel they detract from my reading experience and in fact can often completely ruin a good post. if your going to be that much of a grammar troll gtfo out of here and go back the the RSOF where you belong.
