The quick, snarky answer: they're baby name book authors.
The longer, slightly snarky answer: 99% of name book/sites can't be trusted as long as they have the word "baby" or "child" in the title. These sites tend to cater to parents who seemingly can't think of their child being anything but a baby, and aren't interested in etymology at all--only in a cutesy, fluffy meaning.
Now, given that clientele, I'm not surprised that most of these sites (which are, usually also commercial...) are just too lazy to give a darn about true meanings. So they (excuse me) pull meanings out of their butts, or take a meaning that was falsely derived and perpetuate it (like Katherine's "pure" or Brendan's "smelly hair"). Oh, and don't forget to make sure the name meaning's only one word long!
As for "awesome" itself... Maybe oneway21001's interpretation is right? I don't know, to be honest.
