An easy way to find content to write about that is highly-searched is to visit the Hot Trends Research Tool.

The 'How to Use This Site' page explains it all well, but basically, this is a pretty cool website.

First, on the main page it lists the most-searched phrases from Google (using Google's Hot Trends), updated every several hours.

Then, if you click on any one of those keyword phrases, it takes you to an individual page that has a bunch of information about that niche keyword/phrase.  There are blog posts, forum threads, news items, Yahoo Answers questions, YouTube videos, etc., all about that keyword phrase.  There are also some Google Insight trending data on there.

That gives you a great way to research a hot topic all on one page.  You can write an article based on what you're reading on that page, and even include an image or a video.

It even shows you any Open Yahoo Answers questions so you could post a reply and a link to your new blog post that you just wrote.  Since it's a highly-searched phrase in Google, it stands to reason that Yahoo Answers is getting searched, too.  (Not to mention that Yahoo Answers do show up in Google searches!)

It's a handy little tool for researching hot niche keywords.  Bookmark the site, and refer to it often, since it is always updating with new searched keywords.
