Glad you guys started this thread. I have seen a few of these (like Dr Hans and David Heath), but others I have not and will check them out.
On occasion I will turn a vlog off quickly if it has no appeal for me (like a smoked beer for example), but the only thing that makes me run fast and stay far away is some Yahoo passing himself (or herself) off as a super pro magnificent omniscient brewer, and going on and on about what company sent him equipment to demo (and of course feature). There are a few super amazing people out there and we mostly know who they are. They have written books, have well known recipes, are often quoted ... But getting a go pro camera for your birthday does not make you an expert. OK - I'll go crawl back in my hole now. Brew on !
