Not yet, but there are a few major things that will change that in the coming months. I am kinda sad that a development community hasn’t sparked to explore it like around Nostr. Hard to say why that is exactly. But I think the potential remains huge and the mobile engine has improved a ton. After it gets fully cleaned up, they release a file transfer app, and Pear Credit drops, things could change quickly.
I’m not counting them out yet at all. Still trying to build a project or two around slashtags and Holepunch.
