Sometimes language barriers can be hard, but with the internet everything is so diverse now that I think everyone's grown more understanding about it. A bonus for you - not only will your technical skills improve as you write, your mastery of English will too!
Also if you're really concerned about something coming out correctly, I bet you could find someone who would be willing to help if you put out a call for a proof reader, for whole articles or just for portions of writing.
Glad you finally started blogging, I look forward to reading your work!
