Avoid using SMS abbreviations in blog post and at least run the post through a spell-check in MS-Word before publishing. If the bloggers cannot take the time out to write proper English, why would the readers bother reading through that cryptic puzzle?
People come to your blog out of choice and not any compulsion. If you remember this, the rest is not important enough.
