Usage of proper grammar in blog posts

I just went back and read one of yesterday’s posts, and I caught some grammar errors, typos, etc.  As my time is limited when writing these posts, I usually don’t go back through and revise/edit the posts.  While I try to write as properly as I can, all my posts will be first drafts.  When I write an actual technical article, I will revise the article and correct any errors that my present themselves before publishing it.
