I see there is a lot of content posted on lemmy that points to different instances of peertube but I often find it difficult to find it within my instance. What tools are there to search for content within instances? Or to see if an instance has another one blocked? I love that in Lemmy I can just search for global communities and make the connections i want. And my strategy in Mastodon is to look for hashtags that reflect my interests; But find this particularly difficult in peertube instances.
