Piero Bosio Social Web Site Personale

I feel like I'm not understanding something as I begin to explore #pixelfed. I signed up to an instance. Made a profile and downloaded a mobile app (most of my exploring will be via mobile). Then I spent some time wondering why it felt so stunted. Seems to direct the user fo a 'local' feed, which I assume is boxed to the instance. There's a global option but it seems to provide just as limited search results. Tried a different app, no change. Tried on a mobile browser. Same deal. Briefly tried a PC browser... And I'm still struggling... What am I not grasping? Is it the instance I chose?
For example: searching a hashtag of Gaming, Linux, PC, PlayStation, SciFi, Books... etc gives me a handful of results. Sometimes up to like 12. But there's no way pixelfed has as little as 5-12 results across instances for above mentioned subjects... Right?
