I still can't believe my eyes whenever I see logos in all shades of design crazies and nuances.
For one, I'll state it again, your logo shouldn't describe what you do...
Of course, there are ways we designers intelligently fuse some known icons into logos to make them distinguishable out there.
But it's done intelligently and you wouldn't even notice at first glance because it's very simple and that's the keyword here.
SIMPLICITY.
Your logo should be as simple as possible, and invariably that means removing anything that makes the logo bogus and not easily remembered.
Your logo should strike a chord in your customer's heart, it should be clever, something their minds could wander to when they are about to sleep at night.
