Helium users: where do you get articles ideas?

I often get my ideas from rating the article of other members. I never copy from them, but use their ideas as inspiration for my own. Also, I scroll through the categories and try to find topics that interest me... things I know enough to write about. Sometimes I choose a general topic and try to elaborate on it. I've been wanting to write poetry there, but haven't had time as of yet. There are a lot of great poets there if you get the time to read some of the poetry, check them out!
