I absolutely agree with you. For me, good grammar is very important. I see a lot of people in the internet nowadays, writing content that has some horrifying grammatical mistakes. They make mistakes with the most simplest of sentences and it shows that they aren't really good at it. They mix up all the tenses and make it look like it's gibberish. I'm sure they know what they are talking about, but fail to communicate.It doesn't matter whether you're writing or speaking, Grammar for me, is very important.
