There is this novel kind of (hopefully) "scientific" journals that publish any received papers right away without issuing an acceptance or rejection. Instead of pre-acceptance peer-review, there is post-publication peer-review, in which the authors keep improving and correcting their already published article based on the newly received reviews.

2. Do you consider them scientific enough?
3. Can they compete with or replace conventional scientific journals?
4. How can these newly formed journals get better?
5. What else?
