If you are, there are a couple of things I can suggest:
First, you can share all the ideas you've had but aren't actually going to do. As we discussed in class yesterday, there's nothing wrong with creating a virtual simulation of an editor's office.
Second, you can take a look at articles written by Literary Journalism students. Not all of them were written by students in LJ20, but they give you an idea of the range of possible subjects you can work with.
