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.
Group Sites or Social Network Sites. There are usually dedicated sites for different groups depending on what they are doing. Social Networks are much broader, but groups within them like scrapmoms, scrapsisters, and so many more usually share their ideas and projects. It is up to you whether you will join any group if you want to get more details and interact with the people within the group, but you will get templates in there.
