I’ll start myself: I’ve been quite interested in Esperanto recently, and I am thinking of starting to actually learn the language. Esperanto is just really interesting to me, because of its history and size, compared to other conlangs. I don’t believe it will become the universal world language, like once was dreamed. And I do think esperanto has quite a few shortcomings when it comes to being an international auxilliary language. The reason I want to learn it is more just for that history and culture.
Another conlang I’ve been interested in for a long time is Toki Pona, and because it seems so easy to learn, I might start learning it too. The community for toki pona seems especially welcoming and wholesome, so that’s a plus too!
