In my limited experience as a writer, I’ve written for five different websites. For two of them, I had an editor who would review my work and decide when it was a good time to publish it. For the rest, I had to proofread my own work, and send it to someone who would simply publish it on the website without checking it over first.
The two publishing experiences are very different, as having an editor makes you lazy sometimes; you leave sentences that don’t make sense in the article, and you sometimes don’t correct grammatical mistakes because you know that someone else will catch them. Writing without an editor forces you to proofread your own work, and make sure that it’s at the highest quality possible before sending it off to be published.
I recommend getting used to working without an editor, and forcing yourself to produce high quality work that is, for the most part, error free. This way, working with an editor can become a luxury that catches the few mistakes you do make, and makes your life just a little bit easier.
