The Weissman score is less than worthless, it "isn't even wrong". This comes up in most HN discussions about compression algorithms and I'm waiting for it to go away.
Edit: Even the above got downvoted and I get reminded again that HN is full of stuck up, overly sensitive and unhumorous engineers. With the exception of this being a great place to find interesting things to read the community aspect is uninviting and unforgiving.
Comments about being downvoted are also almost always downvoted. The comment guidelines actually warn you that it's a bad idea.
