Victoria Clarke, in her analysis of telnet talkers, states that capitalization is important when people write LOL, and that "a user who types "LOL" may well be laughing louder than one who types "lol"", and opines that "these standard expressions of laughter are losing force through overuse". Michael Egan describes LOL, ROFL, and other initialisms as helpful so long as they are not overused. He recommends against their use in business correspondence because the recipient may not be aware of their meanings, and because in general neither they nor emoticons are in his view appropriate in such correspondence. June Hines Moore shares that view. So, too, does Sheryl Lindsell-Roberts, who gives the same advice of not using them in business correspondence, "or you won't be LOL".
