I don't know how I personally feel about HFT. I don't have a high enough view of the system as a whole to make a determination if HFT is or will be a problem.

But the mention (http://www.cnbc.com/id/100809395) of Reuters selling data to customers 2 seconds before the conference calls (which occurr 5 minutes before the public receives the data) unsettles me a bit. Two seconds isn't a long time except when you consider that HFT operates in milli, micro, or maybe even nano seconds.

I am not sure whether I would go as far as to consider it insider trading, but I do think the conference call and the data meant for HFT should all be released at the same time as the public data.
