#kbin has managed to pike my interest.
It's far from perfect and missing many features, but it does looks promising.
The biggest drawback is the lack of mobile app yet. The mobile browser experience ain't bad though.
Regarding the /topic@dom.ain example, it looks so much better than the bunch of @s we have now!
All the information @Shortcake is compiled in the magazine m/kbinStyles.
You'll find additional goodies there, and if you come up with the modifications, you're welcome to post them!
