I'd like to give you an example: I recently wrote an article outlining several ways to get out of a writing slump. As I was writing that article, I came up with about 7 or so ideas for getting your brain out of a creative rut with your articles, including some article template ideas and some writing productivity techniques. I submitted the article, and then thought__ "Each of those ideas for getting out of a writing slump needs to be elaborated on and explained further. I can do a new article for each idea." And so I did__so far I've bounced 4 or 5 articles off of that first article, and I have even more ideas that I've gotten from that first article that I haven't written about yet.
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.
