I stay away from Twitter and Facebook. Even a NASCAR driver lost his career because NASCAR objected to his mild comments.
Good for you.
I see all kinds of ways how what people post online can come back to haunt them. I foresee a time, for example, when insurance companies might employ some algorithm to determine if an insurance applicant might be a high risk based on what the applicant has posted online.
Or even based on their shopping habits (charging a six pack once too often and you might be a higher risk for drunk driving).
Likewise, could affect whether an employer might offer you a job or a promotion.
I also wonder if what you post might be twisted and used against you if arrested.
