YT=
When words are not enough to express what you want to say, then mentioning YT to anyone will give them the prompt to open and search for a video that you may be referring on the tweet. Just do not forget to include a link at least so that they would have an idea on what is being discussed.
在Twitter上要寫字數太多馬上就要寫不下的時候，你寫YT就是讓人家打開YoutTube去找你說的視頻啦。千萬別忘了附上你所說的`視頻地址哦。
BTW=by the way

TMI=Too Much Information
信息量太大
Since Twitter has only 140 characters. However, there are a few people that could share so much details in so small of a space. Information overload in social networking sites actually happen when the individual finds it hard to stop disclosing details, even if there is no need to have it shared to others.
Twitter只能發140個字。但是有的人會在一條消息內擺出太多無關緊要的細節內容。有人會經常會忍不住要往發言框裏塞內容，即使這些內容是完全無關緊要的。
FB=F

沒錯，FB就是F的意思。其實Twitter和F一起玩也是很酷很時髦的。
