I&#x27;ll disagree. I&#x27;ve had people come up to me and mention that they remembered my posts on XYZ mailing list. Said mailing list is a huge, public list and I might have posted on it a dozen times. What you say and how you act can definitely have a positive impact on your career. I haven&#x27;t looked for a job since college.<p>I doubt the negatives are as impacting as the positives, but I&#x27;m sure they do exist.
