Is looking at the dot of a green laser pointer, dangerous?

the 5mw and 10 mw are not dangerous at all unless shone at eyes.
the lasers that actually start giving action is the 200mw or greater ones

I think people were a little confused by what you meant. I'm assuming you mean looking at the dot (i.e. reflection) rather than pointing it at your eyes. Pointing ANY laser at your eyes is dangerous, however its reflection off of objects is different.
5mW: Not dangerous to look at the dot.
10mW: Same as above.
100mW: Extended periods of time will have temporary negative effects on your eyes.
150mW: Same as above.
If you're pointing any of these at a darker object (black, dark blue, etc.), then more of the light will be absorbed and it will not be as harmful. Make sure to not shine it at a green object, as the majority of this light will be reflected.

You should be OK at 5 and 10mW. 100 and 150mW are getting a bit interesting. As long as the scatter is relatively generalised (i.e. no mirrors!) and you're not looking at it from too close you should be OK. Just don't stare down the beam.
