The meeting this morning was the first outside feedback I have gotten on it. The big issues he brought up were all expected and so didn't feel too threatening. The worst part was his comment on my lack of editing. He went through the thesis finding lots of small grammar and editing problems. His comment was that I should work to eliminate these from my writing before I hand stuff in to professors because people will judge me negatively because of these small errors.
He makes a good point, but I'm still somewhat frustrated because I would have appreciated this advice during my first year at grad school. If this is a pattern, why hasn't anyone else mentioned it during my four years of grad school? Also, I already showed the thesis to my adviser and apparently she didn't catch these errors. Maybe the problem was more prominent in my thesis because I dislike the project so much that I did a poor job of proofing, but I suspect that I have some blind spots when it comes to grammar. For example, I'm aware of the misuse of "it's" and "its" but in my own writing that isn't something that stands out for me as a glaring error. Split infinitives? I know they exist, but how to spot one? I'm not sure. (This makes my editing of undergrad papers somewhat ironic. Often I can tell them that a particular sentence is incorrect, but couldn't explain to them why.)
I need an editing buddy, someone who is willing to trade drafts with me. Beorn and I do this sometimes, but I would prefer having a backup person. And I need to come up with some additional strategies to improve my editing of my own writing. Generally I just take a break from whatever I'm writing, leave it for a day or two and then reread it slowly for errors. I know people say reading it out loud helps, but the best I manage is mumbling it under my breath.
(Blog posts are posted as is, so I'm sure they are riddled with grammatical errors.)
