I think Jason is wailing too much.
Yes, you do have to sift through sometimes, but the knowledge is here, sometimes a little unrefined, but very present.
I used to read CLeanfax and ICS but many of their articles turned out to be nothing more than a marketing piece for a cleaning method or specific chem line. Reading one the other day about VLM, turned out to be a page long commercial for HOST. A few nuggets of useful info, but that was in the first couple of paragraphs. So, I would look outside the industry.
