I agree on the goal, but I think that instead of a section for beginners it would be best to support Tags on the posts.

So you can simply tag any post with "beginner" and then when someoan search something, filter with that or with any combination of tags.

In the long run post will be better sorted since anyone can filter the main feed to match their needs.

To avoid people to tag with to many categories maybe it will be better to add an increasing cost to any additional tag (1st 1sat, 2nd 2sat, 3rd 4sat, ...).
