By reading this post, I think your English is very good, so don't worry :) Learn, practice, write, and don't be afraid to make mistakes - they are OK as long as people can still understand you and learn something useful from your posts. It's all about programming after all, not about being perfect in your use of natural language :)
I recommend to write or paste your post to Microsoft Word before posting. It will find your spelling and some grammar errors. Then you can paste it to Google Translate and translate it to your native language, to see if it still makes sense. That's the way I do it with all my blog posts.
