In the past five years, the number of known globular cluster
pulsars, most of them of the millisecond variety, has nearly doubled, to a
total of over 300. The main reasons were the commissioning of the
extremely sensitive FAST and MeerKAT radio telescopes, and increased
computing power applied to the searches themselves. In this talk I’ll
mention some of the fascinating exotic systems that have been found, and
discuss the importance of long-term timing of these systems. In
particular, timing observations can provide extremely constraining mass
measurements for some potentially very massive neutron stars. These
pulsars strongly constrain the equation of state of neutron star matter
