For example, why type "lyke" instead of "like", or "iz" instead of "is"? It's just silly.
That is what i dont understand, both words contain the same amount of letters why not just spell the word the correct way.

Someone mentioned it reminds them of baby talk, i cannot agree more. Ok it might be understandable coming from small children, but when grown adults are 'talking' in 'lolspeak' it is just irritating.
