Should probably let it lie, but feel compelled to wade in:
The original post stated that Spectrum's current WIP uses 'extensive glossaries and pronunciation guides which are quite vital to the understanding of the story'. He asks about people's experiences of glossaries, whether they read them and what they think about them in general.
Given these questions, I think those who don't like the use of extensive glossaries have just as much right to give their thoughts as those who advocate them. No one is claiming to be a 'writing guru'.
The question was asked, thoughts were given; there's no need for uncomplimentary personal comments.
Good luck with the WIP, Spectrum. From a marketing POV, perhaps you could also produce an encylopedia or 'companion' for your world, in addition to the novel(s)? Could be a good way of syphoning more money from those pesky readers
