No, but in general someone who takes the time to think and speak in complete sentences appears to be more thoughtful and thorough. I don't know about you but all other factors aside, I'd be more comfortable handing away a portion of my company to someone who says "I look forward to working with you" as opposed to "lol u and i will do gewd <3"

Why should we assume that this writing style is evidence of optimization rather than plain skill?
