Dave, Welcome to HubPages!
At the top of your profile page, in the black bar click on "Explore;" then on the drop-down, click on "Articles."
At the top of that page, you will see "All Topics." Choose one that you know about. Perhaps you can read some of the articles published under that title to give you an idea of other writers' work (that's up to you).
Again, welcome aboard and Happy Hubbing!
