Update Related Projects docs?

[jab]

http://plim.readthedocs.org/en/latest/related.html lists several related projects, but some of them give 404, and most of them haven't been updated in a long time and may be abandoned. Would you like to prune that list, and for the remaining ones, add a short bit explaining pros and cons / why you would choose one over another?

Context:
I just discovered Plim after first finding PyJade, then hitting syrusakbary/pyjade#70, realizing not having mixins/macros was a deal-breaker, and deciding to look for an alternative. So far Plim looks like the best option, but I wanted to confirm my assumptions. Thanks for your work on Plim and best wishes.
