I believe that this mega-thread should continue simply because it's the greatest repository of SGS developments for NZ owners. As the developments for the Galaxy S are evolving, so does the thread, making it of great value to the advanced user while the earlier legacy material is extremely useful for the beginner.
With February's announcement of the Galaxy S2 looming, the original Galaxy S's development will inevitably slow and the thread will subsequently reduce in importance, thus becoming an archive rather than a living resource. So it will 'die' naturally as a consequence, making the locking redundant.
Thanks for asking though, instead of simply locking without consultation - very much appreciated.
