I have a suggestion on how to pay authors (bloggers) for useful content. In the user profile, you need to add an ID to AdSense (maybe other systems, I did not recognize this, but this scheme will work with AdSense).
The point is that when viewing a blog post will be broadcast advertising from the account of the author of this post.
The benefit of the author is that the Habr's audience is larger than the audience of a single blog. Editors benefit from obtaining high-quality content (the quality determination mechanism already exists and works quite well).

And, perhaps, another thought. Blog posts, if a certain rating is reached (or, if desired, by UFOs), could be transferred to the main tape. In general, make a blog "sandbox".
Now, of course, people write to the tape, but somehow everything is not made transparent.
