Blogs R Writing!

It's my contention that blogs are a form of writing.  (It's my intention to exploit this form of writing for fun and profit, if possible.)  What I don't ascribe to is the apparent notion by many other bloggers that spelling and punctuation are unimportant in this format.  Admittedly, I know of no other blogger who is as antique as I, however, that's no excuse for not even using a spell checking program or feature on entries.  I feel certain it would catch "ever" spelled "evar" and the confabulation of "purpose" and "proposing" into "purposing".  Why do these people expect to be taken seriously?  How do they expect to find employment?  Am I seriously out of touch with the real world? I might add that I have a thirty-something daughter who emails me frequently.  She is neither a writer, nor even a college graduate.  Nonetheless, I don't recall a misspelled word in her messages.  She seldom writes incomplete sentences, and she has never appended "I'm just saying" to any comment.  I'm just saying this is a complete mystery to me. Illuminate me, please.
