  • n. The point at the centre of a system; an average point, weighted according to mass or other attribute. The term is usually used in astronomy for the centre of mass about which a system rotates, for example, the moon and the earth rotate about a common point within the earth but not near the centre. Jupiter and the Sun rotate about a common point just outside the surface of the Sun.

  • At a time when more and more dead-tree newspapers and magazines are closing down, or going purely online, and when more and more online titles are starting to run bloggers as part of the mix, it seems to me that the barycentre of digital publishing is mostly certainly moving deep into the heart of the blogosphere.
