On the contrary. Floats can't carry much. You can't work metal without a
forge or way to melt and carry the metal.  No ceramics.  Your kind of stuck
with gases and remains of other life forms or debries.  The complex heavy
materials from metals, bricks, glass, etc needed for technology, especialy
high energy technology, would be unavalible.  Worse, if you could get some,
you'ld have to drop them to keep from geting draged down.

How earth like do you want?  MOst of earth ecology is pretty alien by our
standards (Hint: only a tiny fraction of earth biosphere is part of our photo
synthisis based ecosphere.)  The stuff swiming in Europas oceans could be
pretty big and complex.  Could be similar to our deap ocean life.

As to exotic chemistries (silicon, boron, etc..) they don't seem to be that
active in basic chemister, or interstellar space compared to carbon bases
componds.  So they might be very rare.
