I used to in the beginning but soon realized it's either kinda dead (people don't use it, people from lemmy don't even see it) or completely filled with spam (because the magazine has some generic tags).
It also didn't work reliably and it wasn't clear which posts go to Mastodon and which don't, but that might have been resolved since.
It's a neat idea for small discussions or questions that don't warrant a thread, but it needs better implementation and wider adoption in order to be actually useful.
