I am about to get nerdy here. To my friends, fellow blog readers, and grammar geeks:
I urge you to read, evaluate, and adopt consistent usage of the Oxford comma on your LinkedIn profile.
Not to use it every so often, or irregularly, or in one section but not another.
Because? Well, people evaluate your LinkedIn profile, make an impression, and can get really granular, like noticing typos, or spotting inconsistencies, or worse, discarding you as a contender, a prospect, or a partner because of lack of attention to detail. You are always, ever, and constantly being evaluated for your attention to detail.
As you can see in this article, court cases can be decided on the Oxford comma.
Make your case, be consistent in your message, and contemporary in your grammar, style, and syntax.
Please, please, and please use the yellow pencil above.
