Blogger spell checking

As is relatively obvious, I use the popular "Blogger" service to post my blog. One of it's features is a spell check. Oddly enough, it didn't recognize the word "blog" when I spell checked my last entry. That wouldn't be surprising for the spell check in any other program, like Microsoft Word, since "blog" is a relatively new word. But you'd think that the people who write the software for the "Blogger" service on the "Blogspot" websites that create "Blogs" would have that in their spelling dictionary...
