E-mail etiquette

Whoever came up with the idea that all e-mails are informal, and thus, can be excused from any spelling or grammatical errors should be ostracized from the community.

For those who work in a corporate environment, I’d guess about 90% of communication with co-workers is done via e-mail. So, if you’re a lazy e-mailer, you come across as an idiot 90% of the time.

Come to think of it, why does “informal” mean you get to stop caring how to spell? Shouldn’t spelling something properly be a natural occurrence? I’ve heard a few people blame their usage of words like “differance” on it being “just an e-mail,” but really… everyone knows the truth.
