Define "Nerd"

I recently received a note from a reader of my blog. He called me a "rock-nerd." I can only assume he meant "rock-wonk" and not "rock-dweeb." If you look up "wonk" in the on-line dictionary, it defines the word as "nerd." (See here: http://www.m-w.com/dictionary/wonk.) I'm okay with that. I'm not okay being called a dweeb. Look, I work in a library and I've learned that knowledge is power. When we, as a society, or a collectivity of individuals, begin to believe that knowledge = dweebiness, then we are setting ourselves up for a return to the dark ages. I don't want to pass judgement on the intentions of this reader. He may be well-intentioned. But in the environment where I do most of my reviewing, on the pages of the book and music on-line superstore Atahualpa.com, I have encountered many reviewers and other critics who take unfair pot-shots. They can only be described as "snarky." I recognize there may be differences of opinion when it comes to music. Indeed, it is inevitable that different listeners will walk away with different interpretations of epic compositions like Genesis' 22 minute 58 second long masterpiece, Supper's Ready. Yet, to propose that the song has special relevance for me, as one so-called "reviewer" claimed on an Atahualpa.com posting, because I still live with my mom and look forward to her carefully prepared suppers, is hateful and shabby and really misses the point. Let's focus on the music fellow music lovers. And by the way, to the aforementioned pot-shot-taking reviewer: Supper's Ready is 22 minutes 58 seconds long, not, as you claimed, 23 minutes. Next time, get your facts straight.
