Category Instead of Title?

Sure.
You can show, as a call to action, the title of the post or the topic your posts.
Talking about the categorization of the topic News@me works like that:
At the moment of publication, through News@me, it is possible to associate special topics to the articles.
The topics are insertable directly from your CMS.

The widget is linked by default to the News@me topics but if there is not a News@me topic then it is linked to your editorial tags or to the categories of your site, automatically.

So, if you don’t want to use specific News@me topics, you can go on tagging as usual.
