(A), your English won't improve unless you make a lot of mistakes and correct them. So just write! (B), There are quite a few native speakers of English whose writing is superb but who can't spell worth a damn. I have often wished that these folks would give edit permission on their blog to a fan or two who could sneak in and edit the grammar. If you can find (or hire, cheap) a person who will do this for you, there's nothing wrong with it. Pro writers all have editors... usually several editors. But you'll find that it's easier to want cheap or free editorial help than it is to find it. So don't worry too much about it. See Step A. (C) Your English reads just fine to me. (D) Why not blog in your native language occasionally, as well as in English? There's nothing wrong with having more than one blog. One big point of blogs is to wrangle over your own ideas by writing them down. You might as well do that in a language which you are comfortable using. There may be other native speakers of your language who would be ecstatic if a tech blogger showed up and started writing things that they could read comfortably. Not that I don't understand why you'd prefer to use English for a lot of things, just as many people prefer to do their writing on news.yc and live in a startup hub.
