Ok. I don't see the current size as that critical - its also due to markup and reference, the Tea culture has obvious geographical-specifics-list structure, so a tired reader can skip it. And Tea is a huge topic.
IMO starting discussion on discussion page would have been enough (the coloured boxes linking to almost-nonexistant articles are a bit distracting for the reader), but that doesn't matter. I think we generaly agree on the move/summarization of tea culture, now what remains to be the done is the real work - writing the summary -)
