In 2004 https://paradies.jeena.net/weblog/2004/apr/ersteintrag I started my blog in German. I have a migration background (at 11 years old from Poland to Germany) and that made so I would do a lot of spelling mistakes when writing, even though I could express myself fairly OK. Writing a blog was a way for me to get better at it, and I would encourage my readers to tell me when they found something odd.
Because I moved to Sweden just about a year later, I started a new blog https://jeena.net/something-new where I would write in English, because I thought then both the people from Germany (to a lesser extend) and the people I know in Sweden would be able to read my blog.
It was a good decision to switch to English (which back then I didn't speak fluently at all, but writing was ok), because 5 Years ago I again moved countries, now I'm in South Korea and am still blogging in English.
It definitely helped me to learn English, which now is my main language at work and at home.
