I use 8gb on my mid 2010 MacBook Pro and find that it needs to be rebooted every so often to clear the memory. Since Lion OS X likes to hog all the RAM for some reason.

Using available RAM is good, not bad. Why do you have those 8 GBs of RAM if you want your system to starve (read: use more _slow_ HDD) and use the half of it? It's OK when OSes use all the RAM for caches and buffers, they are smart enough to invalidate them (or move to the SWAP) if some application needs more memory.

After a program terminates the RAM is returned to OS X but it will not allow other applications use any of it. It is a bug with their virtual memory. It will say there are gigabytes of inactive memory but continue to use a swap and not allocate it.
