Context is often not very clear with this word.
Also, point me to another word that means the same thing and I'll stop not-literally dying on this hill. 'Actually' is close, but seems to ignore the figurative meaning instead of complementing it.
Words change, but in this case the language seems poorer for it... and I say this as a Saffire-hating descriptivist.
Have we had a "literally" thread? I should probably stop shitting up this one...
Edit - chose exactly the wrong word. Is that irony?
You can use seriously, factually, actually, honest-to-god, objectively, really, truly, certainly, etc. But you'll probably soon recognize that people use those words to mean figuratively as well!
I do not know what you mean by "ignore the figurative meaning instead of complementing it".
The language is not poorer for it, I do not know how Mark Twain, F. Scott Fitzgerald, James Joyce and Louisa May Alcott made the language poorer for using the word in such a way. Most people would say these authors have added to the English language.
As the editor at large of the Oxford English Dictionary says:
The one sensible criticism of the way `literally' is often used is that it can lead to confusing or silly-sounding results. In this case, the answer is simple. Don't write silly-soundingly.
In fact, he points out that the meaning that you ascribe to "literally" is already a figurative use of the word.
In fact, the literal meaning of `literal' is something like `according to the letter.' So when we use `literally' to refer to something other than individual letters, we're already walking down the figurative path.
