I mention this blog for several reasons.
TeX and LaTeX would benefit from the production of a topic map that eased users from less capable systems to a more full featured publication system.
To that extent, this blog would be an excellent starting place for gathering resources for such an effort.
Most of the major academic houses require the use of TeX or LaTeX for publications so if you want to publish about topic maps, that knowledge is a presumed starting point.
Knowledge of TeX and LaTeX will give you an example of how a well designed system can prosper and grow over time. Something to aspire to.
