You're right.  Imperial is now days used as a "code word" and marketing term for a higher than average ABV of that style.  I know first hand.  I use it on my over the top red, or Imperial Red Ale which is 9% ABV and 80 IBU's.  Most, but not all "imperials" are usually higher hopped like andyjr said to balance the extra malt and alcohol presence.  but does it really matter what a beer is called as long as you enjoy drinking it??  I mean come on, I really enjoy Bear Republic's Red Rocket Ale.  am I not gonna drink it because it says red rocket on it?? hell no, I actually bought it because of the name.  It's all marketing.

Just as it's important not to fall into the 'BA-esque' habit of preemptively turning your nose up to anything that isn't "Imperial", it's equally important not to reverse the situation by doing the same for beers that ARE labeled "Imperial".  As brewers, I think it's important to that we strive to accept and appreciate the entire gamut of beers.
