I think the following generally apply when communicating via the internet, whether using a computer or personal wireless device.
Texting via cell phone: Lack of capitalization and use of short hand (number ‘4’ instead of word ‘for’) is acceptable due to the high difficulty of using a phone pad.
Instant messaging (via computer): It’s a private conversation and not subject to the usual rules of grammar beyond what are needed for understanding.
Computer Chat rooms: These are semi-public conversation so proper grammar, spelling, and word usage are considered a sign of intelligence. However typing speed is of importance and sometimes that need trumps the desirability for proper grammar.
Computer message boards/forums: These are semi-public conversation so proper grammar, spelling, and word usage are considered a sign of intelligence and respect to one’s readers. The proper use of the English language is understood to be an element used in judging the maturity of the poster and the importance of the post.
Computer Blogs: These are public forms of communication. The individual is free to express himself (within the guidelines of the service providing the blog space) as he sees fit. He should be prepared to be judged by his writing style.
