Every day people say, “I wrote some blogs” — when they mean, “I wrote some posts.”
Grr. Folks, learn the terms.
A blog is the whole thing and a post is one story. Just like a newspaper is the whole thing and an article is one story.
You wouldn’t say, “I wrote a newspaper” when you meant, “I wrote an article in a newspaper.”
(Not convinced? Does your blogging control panel say new blog or new post?)
