I've never had a private comment complaining about the facilities in a
general way except from you and Josh Drake, though obviously I field
bugs and questions from users frequently. I regularly get emails saying
thanks, easy to use, much easier to manage than any other form of
replication. Most frequent comment is "I was told it was really hard,
but I see now that it is easy to understand and use".

People with HA or backup experience from other databases usually have no
problem understanding the concepts or the implementation.

That's OK. Wanting it to be different is the first step. I want to
improve it as well, though without removing features.
