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.
Alternative Homework for Blog Owners: Look at your recent blog posts__are there any insightful comments that are worthy of being addressed more in depth in an article? I get ideas all the time from comments on my blog. Or look at your blog comment replies__do you find yourself writing an in depth reply to anyone's question about your post? That is often a good indication of a related topic that could use some more detailed attention.
