I was thinking Medium possibly, but although I have an account I don't use it much. However eightbitsamurai does, I think, maybe some other users. They may have suggestions about good platforms. To be honest I think any blogging service would work but I am sure that you also are interested in being read by users on whatever site you use, maybe? Which would be why you might consider the fanfiction site.

I agree formatting is essential. I know it's a selfish desire but I wish the Hubski markup offered more. However i do realize - I have very specific formatting preferences and desires, which also change depending on my content...and they are probably unreasonable for what is really an aggregation/community site. :)

Personally I have a blogger and have run a Wordpress blog, both are serviceable, I think WP has more options but it is also more potentially aggravating. Check out Medium and see what 8bit has to say.

I'll see what I can pull together for ya!

edit: So I don't seem able to copy text from your story which is also a problem for me, I'd like to be able to put it in word or something so that I could highlight places I have comments.

I was wondering if English wasn't your first language. Can I ask what is? That is for my own curiosity more than anything. Why do you choose to write in English? I am reading a foreign poet right now and they have a big section about how it is not truly possible to correctly reflect poems written in one language when they are translated. I think if I truly want to understand certain poets I should learn the language they write in and read them that way too. But that would be a lot of work for just one poet.

Also wanted to add that verb tense shift ("VTS;" mixing past and present, etc) is a very common error that occurs with native English speakers frequently as well, so while I'm noting it throughout the piece, I think it's more to do with just realizing it's a thing people do and watching for it (as long as you are able to recognize it) than because Eng. is not your first language. Guess I just wanted to say that people do it all the time and not to feel too bad about that one.
