Fair enough, I just figured that as a social network, part of the goal is to connect new people together. You can look at Facebook in the same way you described it. That’s what its original purpose was. To just connect with people you already know, but I feel like social networking in general has since evolved from this. We can look at things like Facebook groups for example where it is more on the lines of what I’m thinking, people join groups that interest them and interact with like minded people that they have likely never met before.
I find the idea of using hashtags as the same.
I can agree with that; but I also think that the average person has not the attention span for long form "macro-blogging" to use it as much as something like twitter or bluesky or microblogging platforms. I think this is why things like vine, tiktok, and twitter are so popular; its because they are all short form content. Things like tumblr, which I'm sure has declined for other reasons, but I'm also sure it is because no one wants to read a whole blog of someone they don't know, but they might read a few words or sentences and if they agree or find it funny or like it for whatever reason, they would be inclined to follow and keep up with that person and may be more inclined to read or give a chance to their content that is of longer form.
