Suggestions are taken on a case-by-case basis, so all of the above may apply.
I think I'm in the minority of writers here, because I actually don't post anything until it is completely finished. I tend not to write in order and I tend to write in spurts, so posting a WIP wouldn't really work for me. So, when people post suggestions in my feedback, I'm unlikely to make major changes to the plot because the story has already been written. However, if I didn't want honest feedback, I'd post straight to the archives. While I rarely change major plot elements, I often change small things - scene orders, dialogue, word choices, etc. Every suggestion is considered.
