The Nerdist is a big geek oriented site full of podcasts, original videos, and geek oriented reviews and articles.

Right, so they're not talking to you. Just like when they post a review on Amazon, they're not talking to you as the author, they're talking to other readers.

This. A simple "like" to the review and "Thank you!" is sufficient if you want to, but don't try to get involved in a discussion.
