Geez take it for what it is alright? I personally can relate with Bill as my company is doing exactly what his company is doing. If anything it just validates the presence of what my company stands for and why we are here.
But hey I'm sure you've got something really useful to do right? aside from wowing us with your knowledge of Internet social groups and anonymous posters.
On most Internet social groups (e.g., reddit, HN, google, amazon) spammers are omnipresent. What an ideal medium HN is should you desire to capture the eyeballs of nerds and technoweenies: then you could sell them books, sell them ideas, direct them to other websites, sell them seminars, BS, etc.
Indeed, what communications channels are _not_ replete with spammers?
And if, as you say, he says "nothing really new", why bother? Shouldn't you be reading something else, something that is more informative to you, something that possibly contradicts your experience, surprises you and adds to your knowledge? Reading what you already "know" is a waste of time IMO.
