How about a section where brewing internet lore is fact checked and either backed up or refuted. There are so many tips out there that it's easy for a new brewer to get confused or maybe a section where the experienced brewer can take up to the next level. When I first started out i was told to ferment at 72f , but only later come to find out that my beer comes out much better when I pitch in the low to mid 60's. I think I was told that so my ferment would at least finish out and I wouldn't fail on the first batch and give up. I would like to see a section that lays out those kinds of differences between what a beginner may be instructed to do and what an advanced brewer should be doing.
BTW I still refer back to the 1st edition of how to brew after 5 years of brewing. I definitely will buy this latest edition on paper copy.
