I'm wondering about the best way to represent text that contains a flyout / tooltip (similar to Foursquare - see image below) but is not a link to another page.
In my case, there are a number of these text links on a given page, so having a tooltip / question-mark icon would clutter up an already clean interface. Should the text be black with a link underneath? What is a good technique for this (below is an example of the text that will contain a flyout)
