For the past few weeks I have been hearing reports of Google not underlining the titles of the search results.
That conversation recently seemed to have spiked up and more and more people are now seeing, well - not seeing, the underlined titles in the Google search results.
@andrewchen were some of the few to tweet about this and include a screen capture.
Google search results without underlines:
Google search results with underlines (like most people see them):
At first it I thought this might be some type of extension removing the underlines from the title but with the number of reports I am now seeing, this has to be some type of limited Google usability test.

IMHO underlines are important for consistency in identifying what text is linked. 'Mystery' links on sites don't aid the user experience. I'm not seeing any benefit in a potential move to none underlined....

The underline part isn't super important. As long as links are obvious (different colour, size or font) then usability would still be fine. Web designers stopped using underlines in main navigation years ago.

Why is Google trying to confuse the readers by not showing the underline?

It freaked me out a bit at first, but now I like it.

I do not think that it should be a problem. Google is trying to test out what is better.
