Bulg? Bowleg? Blob? Bloop?

These are some of the options one gets when he or she searches for "blog" on Merriam-Webster online. The Merriam-Webster's 11th Collegiate Dictionary is out, and it doesn't appear to have "blog" in it, at least according to it's free online site. There's probably no connection to m-w, but it's starting to drive me crazy that online spell checkers don't have "blog" in their dictionaries.
