I had the brilliant idea to use the term "blowg" to refer to a blog that blows. I looked it up online, and found that this term is already in use to mean:
Using your hardly read by anybody blog to copiously praise the work of your friends, usually at their behest, in a vain attempt to create a 'media buzz' around them.
I grabbed that from urbandictionary.com, and couldn't really find any other use of it anywhere.
Anyhow, that definition sucks, and I'm re-coining it to refer to a blog, much like this one, that absolutely blows. I have first use in this context, as far as I know.
