I often look for new projects in the ANN section (although there are few good projects now), the order of ANN's posts is different from other sections. There is a special mechanism called bump. I guess the strange order mentioned by OP in the topic may have something to do with this
In addition, posts are usually sorted in chronological order. I hope to find new projects with potential, not the more well-known projects that have been released before (because their profits are not as high as new projects)
