If you hang out on any forum other than WebmasterWorld Matt Cutts will penalize you :)
Matt's comments are not about your browsing history. This is about following risky advice. If you trade black hat tips you are very likely to be utilizing some risky black hat technique on your sites. It is not surprising that Google penalties will eventually catch up with your risk taking.
I do think that your browsing history can impact your SEO efforts. For example many people forget about personalized serps and don't realize that their assumed rankings are caused by their browsing history which can lead to bad decisions.
