Thanks,
If you are looking for basic grammar or styling review, though, you can check out tools like ProWritingAid or Grammarly. I tried both, but preferred PWA. I currently only use it to do an edit pass on my fiction drafts before they go off to an editor, but it'd likely be decent for non-fiction blogging content as well.
For example, in the course of building my App, I have encountered different issues and/or learnt a whole lot of different things. I end up blogging about it because figuring out the solution was quite interesting which can be fun on its own. The feedback would come from people who read the article or comment if you tweet about it.
Let people comment on your work (via Hacker News, for example), and you'll quickly realise if you missed something
