From those where I actively look for new updates:

• “Heather Potter_ After the War”
• “Harry Potter and the Annotated Story_ The Chamber of Secrets”
• “Harry Potter and the Ritual of Love's Memory”
• “Fair winds and following seas”

And one non-HP (yes, they are more snobbish and having the canon fully in public domain, most of stories are on the commercial sites):

• “The-Sailor_s-Rest-_-A-Pride-and-Don-Jacobson” … Pride & Prejudice meet Persuasion meet Horatio Hornblower, slightly too long and slightly failing on “Show, don’t tell” rule, but otherwise obviously professionally written thing.

My top is New Blood, which is a Slytherin Hermione fic, with lots of exploration of magical paganism.

The next would probably be Harry Potter and the Engines of Change which just finished its final chapter, beautifully wrapped up (though the author says there will be one final sequel). The first story is Harry Potter and the Ticket Backwards. It's a great, fresh take on the "Peggy Sue" genre where Harry genuinely struggles and sometimes forgets things. He's a good person, but a flawed character and makes mistakes sometimes, but the story still has an overall hopeful tone.

BTW, I had problems getting this comment to post, turns out the issue was some weird thing with Lemmy's language setting. I set the language of both the post and my comment to English, and that seems to have allowed it =). I also have my Lemmy account language set to both undefined and English
