Everything has already been blogged. So why not do a quick search to see what others are saying before you draft up that next post? That way you’ll get other perspectives and even more ideas for that ultra witty post to impress all those people who pretend not to read your blog.
If you need proof I searched for “everything has been blogged” and found someone blogging about that… In fact, there is even a shirt!
