New channels of speaking
New forms of communication, such as e-mails, chats, and bulletin boards, have created a channel of delivery that is quite different from formal speech. This unique requirement for speed has caused the standard rules of the English language to be altered or ignored.

I am leaning toward Elision? Are you familiar with that?
Elision is the omission of one or more sounds (such as a vowel, a consonant, or a whole syllable) in a word or phrase, producing a result that is easier for the speaker to pronounce. Sometimes, sounds may be elided for euphonic effect.
Elision is normally unintentional, but it may be deliberate. The result may be impressionistically described as "slurred" or "muted."
