Oh look, lame sarcasm in place of a reasoned response. How unlike slashdot.
"The Microsat movement isn't going to contribute much to space pollution as low lifetime sats deployed to low orbits aren't the problem."
Who said they're only in low orbit?
"Creating an space-based economy and self sustaining workforce"
And what exactly does that hand waving soundbite mean in practise? What will the economy be based on, how will they be self sustaining in a hard vacuum with everything having to be shipped up from earth? Take your time.
