Funny thing with "webwords". We always see them written and rarely get the chance to her someone say it and have to pronounce it. I had that opportunity last week. I said something to my wife about emoticons. I pronounced it emo.ti.kahn and my wife looked at me a little weird. She suggested it was pronounced emo.shi.kahn because it was combining of emotion and icon. Seemingly. Seemingly, to the untrained eye, I can fully understand how you [she] got that impression (Seinfeld quote).
We did some quick searching and found that emoticon is pronounced emo.ti.kahn and is actually a combination of emotion and console. :-)
[edit] Looks like someone changed history in Wikipedia. To get the real history (from what I know) you need to look at the June 5, 2006 entry before it was changed.
Giddy Up!
