Here's a hot topic you could cover

Have you been wishing for some idea that would sell easily to places you submit it?

Well here's one!

Write about monetary issues (saving money, spending money, investing, creative ways to earn it, etc.).

With the economy as it is, people are wanting to know everything they can about this topic. It's usually an easy article theme to sell, but it's even easier now. I'd recommend interviewing someone (check out your local college; all you need is a "Professor so and so" to get in the door most the time) and aiming at small magazines.

It's funny, but this economy problem actually puts money in writers pockets.
