I use PeakD list function quite a bit. I have varying moods for what kind of content I want to look at and the list function works very well. I have a small group of people I have delegated to, I have a list for them. I have my favorite photographers, so I have a list for them. I still use my default followers feed. As time has passed I have quite a few and at times I need to adjust my following feed.
I currently have 13 list. Some people are duplicated on list, because they have different types/styles of content. I don't want my list available for others to view, it is my list. Perhaps for communities @asgarth can make list available for communities and make them viewable for others to see. The top 5 could be under the Team and then in the navigation bad a list drop down like you show. I don't think I would call it Collections though, I see it more as a categories list.
Being able to have meaningful list with short 30 word description would be a big help for communities.
- Fractal Art
- In this list you will find artist that specialize in digital fractal creation.
- Oil Painting
- Here you will find artist that specialize in Oil Painting
That sort of categorization, people visiting can now find a breakdown of the overall community of Art to the various types being offered in the community.
You have some good ideas in your post. By this time next year things could look a lot different and be easier on the eyes and on finding the content that brings people in. Can you see a future where an Artist posting in OCA has as the first tag #oilpainting and then their post is linked/placed in the oil painting list.
Keep pushing, when time comes I am sure someone will help to build/improve it.
