It's amazing how technology, especially the Internet, affects how the written word, as opposed to the spoken word, is utilized. For example, FYI is an acronym that is different than FAQ, these are terms that are mostly used with text messaging, WEB pages or Emails.
It's almost impossible to keep abreast of all the "internet speak" as most of the items are not obvious. However, even though obscure, some terms are more appropriate than others. One of these is RTMF. This particular acronym has many variants but it generally conveys, to the recipient, the message that "I'm a bit lazy and I'd rather ask a question than read the answer".
Although not entirely technical, my favourite acronyn is TANSTAAFL. It implies that when it comes down to it, It's always a question of money. In other words, "you get what you pay for".
