What I dislike the most about modern web apps is the practice of displaying time in a relative format, such as "a few minutes ago," "a few hours ago," or "a few days ago," instead of showing the actual time. It's a relief when hovering over the time reveals the exact time, but that's quite rare.
Since almost all web apps follow this trend, it seems like I'm the only one who doesn't like this method, and I really can't understand it.
