Sorry, but while it may be more acceptable on a message board, it's not becoming more relaxed in the real world. People can absolutely spell what they want but it's a huge deal in some instances. If I get a job application with grammatical and spelling errors, it goes in the "no" pile. Proofreading and attention to detail is part of the job description. If one is used to being sloppy while typing online, it carries over to important documents, as well.
Plus, if someone repeatedly uses the wrong word, it makes them look ignorant and I have a hard time taking them seriously. I hate loose for lose, the interchangeable use of advice and advise, and random apostrophes.
I cringe when I see "wallah." It's almost like people hear a word and want to use it but have no idea how it's spelled so they just make it up.
