From the perspective of a good UI design, it would probably not be good to essentially hardcode these two types of posts to be their own pages. They may be the trending projects today, but 3 months from now there could be something completely different.

Also, separating them out of "trending" is actually a lot harder than it sounds. The UI relies on the blockchain's count of how many posts are returned, so if some posts were excluded, it would not know when to load the next set of posts when you are scrolling down.
