Nope, English is my first and only language. Well, I speak geek a little. We're pretty informal here, though we do try to get the spelling correct. We (Steve, Brian, myself) find most technical content hard to read, so we try for a less intense approach. In this case I did write in journal fashion because I wanted to try to present as best I could what happened/how I felt, not really try to clean it up.
We've got a book project under way to compile info from the site and the majority of readers did want us to correct typo's and minor mistakes, so we'll be reviewing old content and putting more time into proofing new ones. In the interim, if you see something wrong, please do point it out and we'll try to fix it.
