Hello all,

I recently discovered this forum thanks to the google widget and have been trolling for about a week now. The precision inherent in a truly great riddle inspired me to write one of my own. I would appreciate any and all honest feedback. Please Enjoy:

I am the embodiment of precision. So too, must you be.

I’m always at the top of your mind and at the bottom of all your questions.

With a change of position, I can divide the masses.

In fact, you probably wouldn’t be here without me.

Despite all this, on the whole, I’m practically useless.

What am I?

darn it.

I loved the enthusiasm though.

Now on to my next puzzle...
