The only significant difference I would argue for is a matter of degree. The job of an Adwords programmer is mainly delivering better ads (rather than simply moving equivalent ads to the top), while the job of an HFT programmer is mainly about being the first to trade.
Some HFT is beneficial. Too much wastes talent, but is otherwise harmless. I wouldn't advocate heavy handed regulatory solutions, such as banning all HFT - some HFT is useful, and have no faith in the ability of regulators to get the right balance. I'm just giving my perspective that the wasted talent argument isn't a crazy one.
Always interested in meeting new people, will send you an email.
