By know you have read the news, some parent named their new born baby girl Hashtag. This is a really bad idea but not for what you think. It is not that the child may be teased, or confused, or her future cost of therapy. The reason that this is a bad idea is ironic:
If the parents named their child hashtag because they like social media, the name actually completely disadvantaged their child in social media. What do you the child can use as a name in her online identities? dashtag may well be a reserved word. How about her personal brand? I would suggest “www.mymomnamedmehashtag.com”. Because if I were to look for her, and perform a web search for “hashtag smith”, do you think I will find her easily? Or would I get a thousand result pages talking hashtag the social media term instead?
