[slf4j-dev] Logback doesn't work with SLF4J?

[Ceki Gulcu]

While easier on the short run, it would be even more confusing on the 
long run to have two distinct methods of binding.

In case of logback, it has not yet caught up with slf4j 1.8.x. However, 
this will be remedied some time in the near future. Presumably, the same 
will be true for log4j v2.

In case of Gossip, I don't have a good response.
