I wouldn`t care about co-workers finding out. But I wouldn`t use it because of security rules.
In April, I used somebody elses computer to log in a few times. It turned out that TERB got stuck into the Search feature of Explorer`s History. You could delete files, cookies, History, the temp folder, but whenever you put a "T" into the Searh field, a dropdown menu would still appear offering "https://terb.cc", despite the fact that options were set not to save or store anything. No other letter prompted any matches.
It`s not so much that it was TERB, but I was uncomfortable about having introduced any website that insinuates intself into the browser so thoroughly. So the potential of this happening to a computer at work is what keeps me from ever visiting. These days I log in mostly through public computer terminals.
