It's been like this for 2 years or so now. Numbers aren't really why we all come here anymore. It's not great as I can imagine the site isn't attracting many new users as we all came for sales and eventually browsed the forums and made accounts.
I mean I am surprised sometimes when a good few youtubers mention this site here and there in their videos for sales numbers, and some notable channels too like ReviewTechUSA and Farfromsubtle. As well as a few people hear and there refering to it youtube comment sections and elsewhere. Although you are very right about your last sentence I've been using this site just to look at numbers years before I ever noticed the forums and then made an account. Would be great to try and attract more people to the forums of this site some how.
