I haven't really been investigating MAV enough to say if it's got any 
"weird behavior" (asymmetries in tiebreaking, etc). Apart from that, I'm 
a bit conservative with names, but not so much that I can't switch over 
to MAV :-)

There could be another reason to using MJ, though: it's the name that 
was used in B&L's paper. If you say "MJ", then the people you're talking 
to can go and find the paper - and the experimental results - quite 
easily. But MAV? There's not much out there about it outside of Electorama.

Also, a somewhat more distant objection: I don't really see these 
methods from the "iterated Approval" or "Bucklin" POV. To me, they're 
rated methods that use certain statistical concepts (the median 
estimator, primarily) to be better at resisting strategy (and to handle 
monotone nonlinear transformations of the grade scale). So "Majority 
Approval" doesn't explain my way of looking at the method very well.

But: these are objections I can live with. If referring to the method as 
MAV is a good strategy and provides unity, then I will do so. I just 
thought I'd let you know what feelings I notice when I think of "MAV" - 
both the name and the method.
