For "something that is published" (which includes a comment like this) I clearly dislike it too, but for chatting / texting, I realize that I often use it more than my interlocutors, and I'm not sure why. There's a part of lazyness I guess, but also a vague sense of "conveying the impression of a never ending stream of communication", which is closer in my mind to the essence of the chat medium. In French, there is also the additional layer of "using the accents or not".
