Like - Now, the Most Useless Word in the English Language

The word Like used to be quite useful.  It has the general meaning of similarity, or approximation, and also used in a simile. 

They are like minded. - Similarity / Approximation.
It smells like roses.  - Simile.

Nowadays, the word Like denotes stupidity in the speaker.  Like has become a space holder in a spoken sentence, taking the place of 'Uhm'.  Like is also a spoken coma, or mental break in the sentence. 

While I complain about the vast incorrect overuse of this word, it is so pervasive I find myself guilty of using it incorrectly as well.  Those who put it to use too frequently, and incorrectly, sound like this:

I find myself unable to listen past the 10 second mark.
