It might amaze you to hear that I'm fine with "like." It's in the same linguistic family as "well," "know what I mean?" "so..." and "er..." (eh bien? alors??). Such things have a time-honoured home in spoken language, though not in writing I think. They enable the speaker to lubricate their sentences without resorting to awkward pauses while they collect their thoughts. I've corrected and adjusted several things so far in this typed message as I've gone along that you don't see, because all you're getting is the finished product. You can't do that in speech when you're thinking on your feet.

Know what I'm sayin'? :-)
