From Keith Arnaud:

The reactions I recall to my comments about saving posterior
distributions were that Jeff Scargle was very sceptical about
using other peoples posterior distributions as priors since
it would lead to errors propagating. He preferred neutral priors.

Then Tom Loredo noted that it was also important to know the
likelihood functions used. If you took posteriors on two parameters
from different experiments and combined them as a prior and the two
experiments themselves used the same prior then you would include
this prior twice.
