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.
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.
