I went to the desktop to look up something on Google last night (notice how I worded that in a way that no one does to respect a certain web giant’s trademark), and was surprised to not see something: lines beneath the links.
Link underlines have been gradually going extinct on the web for a while now. Google was a big holdout, a strong indicator that those lines were still found to be, by a company that doesn’t muck about with such things, too valuable a cue to throw away. (Though even it had put a toe in the lineless water, removing lines on all but the main entry links, and, for some reason, “Previous” and “Next” in the pagination.)
Apparently, no longer.
