Do you think it’s important to have correct grammar on social media? Why or why not?

If you have asked this question to yourself before, I will give you my opinion.

Like everything, it depends. If you are a business starting a marketing campaign and you are seeking to expand your customers agenda, you may want to use proper punctuation and grammar. However, if you are just posting about your dog's birthday and your audience are your friends and family, you can use bad grammar. If will depend on who and why you are writing.

In general, if your personal social media is also used professionally, you want to leave a good impression to those who may check it for business purpose.

Anyways, it is your social media, not mine. You are free to decide who is your target audience and how you want to present yourself.
