I usually won’t delete or alter comments unless they’re spam or double posted. This is just a list of my preferences and what I consider spam, for a better commenting experience.
Anything irrelevant to the blog entry should be directed to my contact form, which includes comments on the layout, self promotion, competitions, general questions, etc.
Valid, contributive comments are welcome but rude comments are not. There are ways to express yourself intellectually without making an arse out of yourself or others.
I type faster than I think, and can’t proof read to save my life. Comments which point out my errors as a way to pose an argument will be marked as spam.
