Speed writing for Twitter?

Back in my high school days, I had a class which consisted mainly of the entire class copying pages and pages and pages of notes from the originals which were projected on an overhead projector.

Around this time, I came across an article in a magazine about speed writing (or something like that) as a type of shorthand for the rest of us.

It was not a mysterious code, like shorthand, but was just an abbreviated writing system. The main points (as I remembered them from my brief reading of the magazine article) were: dropping all short vowels (hat=ht, hate=hat), spelling phonetically, representing common endings like "-tion", "-sh-" and "-th-" using abbreviations like "Sn", "S" and "T", and abbreviating common words like "the" of "of" with abbreviations like "T" and "v". I also abbreviated the suffix "ing" with a letter that looked like a combined "n" and "g". Abbreviated, the opening of Longfellow's "Paul Revere's Ride" would be written: Lsn my Cldrn & u Sl her v T midnit rid v Pl Rver.

This system wasn't too difficult to decipher. One classmate would even take my notebook home and copy what she had missed during class.

What reminded me of this was Twitter. Trying to get a complex idea into 140 characters leads to abbreviations that have been common for a long time in instant messages: u, 2, l8r. But I wonder if people would understand things like: vacaSn, domstc prtnrSp, dmcrt, cnglmrts, britn s seTng t prlmnts abus v gvrnment fnds. Hw dd Ts cm abt?
