I occasionally spot grammatical mistakes in newspapers in English. I wonder if they don't use any grammar check softwares.
At the same time it reassures me because even native speakers make mistakes, non-native speakers like me can make a lot more mistakes.

By the way Reddit is a really good site to get used to writings of native English speakers. Subreddit, Today I learned, is especially interesting.
I'm surprised by the fact that ordinary people can produce such fabulous sentences. I also like subreddit, books. Someday I want to write a review about a book I am reading now, embracing defeat.
