Contrarian view; the average is still a pretty fine measure, assuming =
one does not over-interpret it, accompany it with a measure of variance =
and only apply it a distributions where it intuitively makes sense (e.g. =
for distributions like a gaussian curve, A-OK, for a bi-modal =
distribution with peaks symmetric around zero probably not so much).

However the same caution should be used for alternative measures, beware =
of the single number descriptions of complex data...

Regards
	Sebastian

P.S.: Often it is not obvious from the beginning how a distribution is =
going to look like, it seems dangerous to summarize to mean + variance =
at that stage before actually looking at the data, however an easy trap =
to fall into especially for sparse data.
