Help please: Network Service Discovery Disabled

[Peter Silva]

Does anyone know of a practical useful service that is discovered by
avahi? I know it is supposed to provide discovery, but it's never
discovered anything on my networks, so I always just turn it off,
especially because it tends to be unhappy about something most of the
time.   I have the vague recollection of it breaking DNS also.
