They used to recommend using the MAC address. This was ok 30 years ago when a computer sat in an office on a desk but it makes it very easy to fingerprint a moving computer as it moves across different networks.
Using a random address (Privacy Extensions) solves this problem though, but do we expect everyone to know what that is and check it's enabled? Mine wasn't enabled by default (on Linux) and I only noticed when a bittorrent site warned me.
