The main reason for posting it is to see what kind of residence the CEO lives in. Is it a mansion, did he recently move to a much more expensive place etc etc. It is public information and when you run a publicly traded company obviously people will look up everything they can about you. I have seen all this kind of information posted on many other boards before. If there is a problem with the address post you can report it and they might remove it if it is against TOS. But I found it interesting and so might some other investors...
Simple explanation from the company would'a sufficed instead, investors are left to rely on 2nd & 3rd source to get watered down info. Transparency has also been will always be the problem w/ this company.
