In terms of reviewing beers, most people have moved to using an app like Untappd. BeerAdvocate, another forum/beer rating site seems to have a more active userbase, but even that is becoming less relevant today as people move away from forum communities.
Is that data on RateBeer of use to them? Are they planning on pouring money into it to position it as a competitor to Untappd? I'm not sure what the goal is. If the fear is they will secretly skew review scores to favor their product lines, that seems hardly worth the effort, as I don't think enough people use the site to drive purchasing decisions to make a meaningful impact.
I think people need to be aware of which beer publications ZX Ventures owns, or owns a stake in, as that will help you identify marketing fluff pieces vs real reporting. The fact that they go to some effort to hide their ownership of several brands they have acquired is concerning to me, but I also understand it is not in their interest to promote that fact. Many people unknowingly buy ABI products without having any idea the beer they are buying isn't in fact locally owned.
