Yeah, my stats have taken a major hit as well. At one point I was getting around 300-400 views per video, now I'm getting less than 200 normally. I'd suggest googling the youtube key word tool. You can type in words that are relevant to the topic you talk about, and find popular search terms that people are looking up, to hopefully increase your view count. That's what I do, and sometimes the view counts will spike past 1,000. I'd try that.
