Using the memory available isn't a BAD thing... Running out of memory is though... That's where swap is useful.

High swappiness makes the system swap out (RAM->SWAP) aggressively (idle processes memory blocks are moved to disk).

Low swappiness swaps out when memory is running full instead.

Experiment with it and find out what setting fits Your usage pattern...

I wouldn't recommend setting the value too low (30 seems fine here so far).
