Sorry for spamming, but seeing that the other OSM-post got quite some traction, I wanted to point out that the OSM-community here is coming to life as well.
For example the mention @shadearg@lemmy.world simply displays @shadearg as a link to https://lemmy.world/u/shadearg, completely obscuring the format of the actual mention.
I suspect that the direct community link may be transformed in a similar way.
