I use it to find inspiration for projects where I only have a rough idea of what I would like to build/make. Usually it’s enough to create a new board, enter a vague search term, add some things that seem fitting to your vague idea and then Pinterest does a really good job in suggesting things similar to the results you already added. It narrows down the search results by what you save.
That sounds good! If Pixelfed or similar implemented that, it could be sufficient. A new fedi service starting from scratch would lack the existing pool of resources since federation only happens when a post gets posted/boosted but after some time it could actually be useful.
