Another way you can go is to create your own templates. You can base these around the types of articles you enjoy or you can visit other directories to see if you can find a general idea that gives you the ability to come up with your own template. Using your own articles may help you come up with your own templates as well. If your articles are along the same lines, you should be able to come up with a number of templates. Those will give you ideas for new articles and that for sure will help you get through your writer's block.
One option that many people don't think about is to use an article template. An article template gives you a general idea and then you have to insert the topic using the idea they suggest. For example an idea would be Methods for Saving X and a topic would be Methods for Saving Money. With most templates you will have the ability to do at least two articles from it until you can come up with more topics. The two articles would be a positive and negative or upside and downside. There are a number of places you can visit for article templates. Some of them supply free templates while others charge a fee for them. You'll want to do a Google search to see what you can find and use for your articles.
