    is there any reason to erase hard drive and do a new install other than selling mac or new os?

    removes useless junk that ultimately builds up on an old hard drive
    just bits and pieces from programs and whatnot

    It's not really something that you should do if you don't have any slowdown problems. Use a program like cleanmymac, they essentially perform the same task.
