Here is something that always helps me have an interesting topic to talk about: listen to NPR's "Morning Edition" or one of their interview shows, like Diane Rehm, "Fresh Air" or "Talk of the Nation" . You will nearly always hear something about a new novel, a new scientific study, artists and musicians talking about their career or their process (ones you wouldn't see in People magazine), an in-depth profile on some other culture, etc. Then you can talk about WHY it was interesting to you, so it's personal because it shows the way you think and what you are interested in, but not "intimate".
You can also scroll their website and listen to separate segments, if you don't have time to listen to the whole show when it is on.
