What do you do when you have nothing to blog about?

I found this informative blog which had a good post about What to do when you have nothing to post about. The blog is titled Blogged up!, but you may know it by it's former title, Third World Chaos.

The post lists 5 great ideas for blogging, when you just can't seem to find anything to blog about. One that I thought was very clever, and which this blog's author attributes to John Chow, was to just re-post an old blog post from the past. If you're blog is more than a year old, it's pretty likely that some of your readers have never read all your postings. So why not just re-post, especially if there's some very useful information that others can benefit from reading.

Another thing I like about this blog is the label cloud and the label listings on the right column. I really need to do this for my blogs. I find it very useful to find what you're searching for.
