Hum. I love to do Random Blogging with my expertise. I just like to give every thing which i felt important to me. Random blogging would be the nice idea.
Here's a few ideas: - search your niche on blogsearch.google.com and see what topics others are blogging about - browse the bookstore magazine racks looking at magazine covers related to your niche - go to Yahoo Answers and search your niche to find what questions people are asking...answer those questions. I have a ton of ideas about how to find content, and how to make it unique and original in my free ebook: Uniquification - Generate Good Content Quickly and Easily You might find it worth a read. (There are even some macros in there that can help automate the searching for you!)
