I'm sure they do. I think that it's more difficult to get bloggers block, or writers block for that matter, in today's world. There is an abundance of information, so finding something that inspires you is much easier now than it used to be. But it happens nonetheless. I think that bloggers read a lot of other blogs. There seems to be an endless supply of material coming onto the internet on a daily basis. You just need to have time to find it.
