As I mentioned a few weeks ago in this post (Bablo in North America), years ago I was involved with something called Bablo. In short, it was the idea that people would get together for conversation and friendship in their favorite Auxlang. Generally people used the various Euroclones and Esperantidoj, because they are mostly mutually intelligible.
I have just opened a subreddit called r/BabloLinguo . "Linguo" was chosen from Ido - a language I don't actively use. This was meant, in small part, to reflect the Spirit of Bablo, which is that even if we each have our preferred projects, we can put that aside and still understand each other.
Nothing is off topic in Bablo (as long as they are in line with the Spirit of Bablo), but you must use an auxlang. Literally any auxlang or auxlang proposal is allowed but keep in mind, the goal is mutual compatibility. If you're posting in Volapük, be sure to include enough glosses that people can follow along with what you're saying.
NO ENGLISH. There are plenty of spaces to discuss auxlangs or other topics in English. The whole point is that Bablo is a place where we can use the languages we're interested in. With this in mind, I agree that it's a little weird that I'm writing this post in English. This may be my last one of this type. One possible exception might be Ogden's Basic English. We've yet to have anybody show up claiming to advocate for that project, but at this point I figure if you're going to take the time to learn it, we can try to understand you.
The Whitelist. In chatting about Bablo with people, it came up that maybe there would need to be a "whitelist" of languages that are specifically allowed. Very broadly, you can use Esperanto or an established Esperantido, you can use basically any established Euroclone. Personal Esperantidos and Euroclones would probably be fine. Projects based on a single language would generally not be allowed, unless explicitly whitelisted. I don't know if anybody advocates for LSF, but that's on our (still hypothetical) whitelist - as is Anglo-Franca, just to make sure.
But mostly people showed up and spoke Esperanto, Ido, and Interlingua. Bablo was started over 20 years ago by an Idist in Australia (I believe). When he suddenly vanished and the original list stopped working, I created a new group on Google Groups which has been inactive for 10 years, but apparently still works. There was also a Facebook group. (It has more recent activity, but it's been pretty quiet too).
If you need me, I'll be in r/BabloLinguo trying to get some conversations started. Come introduce yourself or just leave a coment.
