After reading one of my recent posts, my wife lovingly informed me that I write too well. Actually that's my spin on it; she was saying that I write like I'm trying too hard to sound intelligent and well-educated. She says using words that "most people" don't know is off-putting, and that more people would enjoy reading my posts if I wrote for the masses.
At first, I took the criticism well (I think). I asked for more information about what she meant--what parts of the post in question were too... wordy. (I was going to say verbose, loquacious, or garrulous, but let it never be said that I don't listen to my wife). She explained how she thought I could improve a particular passage, and just like I did back when my mom used to proofread my English papers, I diligently took to the task of re-writing. After polishing out the rough patches - or perhaps, dulling down the polished patches?? - I asked her to re-read it. She said it was pretty much the same, because I had left in two of my favorite alliterative phrases. She doesn't like alliteration, whereas I'm pretty sure I have a psychological condition that compels me to use it.
I was very upset by this rebuff, not only because I'd put considerable effort into taking her advice, but because writing in "my voice" is very important to me. Sure, maybe I'm trying a little too hard to sound like a seasoned arts critic, but that's the kind of writing that appeals to me--the kind that offers a challenging read, that really forces me to think in order to wrap my brain around the writer's point of view. It makes me a little jealous, but I don't even mind if I have to consult the dictionary once or twice. It's a learning experience for me, and I guess being out of college makes me crave those opportunites to flex my mind a little, especially since my current job provides no such exercise.
So I suppose the question is, should a blog be more like a journal, written in a conversational style (like this post, and all of my wife's post), or can I pretend that I am a seasoned arts critic when I write about movies, music, TV, or any other pop culture topics. My defense to my wife was that this is my blog and it should be a reflection of me, but upon reflection, I decided I don't want a blog full of well-crafted essays that no one will read. Blogs are great for getting your thoughts out, but I'm finding the more I do it that what's really fun is getting feedback, sharing ideas, and connecting with people. And since everyone (including me) loves my wife's posts and can't wait to read the next one, maybe I should keep listening to her. It's served me well in the past, that much I know...
which is why I resolved the argument over writing styles with a gesture most magnanimous (look it up, ya lazy bum). To show her I could be good-natured about the whole thing, I replaced one of my so-called fancy phrases with a term from professional wrestling: "acerbic wit" became "sarcastic smack-down"
How's that for writing for the masses?
