Discussion of caption:
1. I like the main article (in this case, "chloralkali process" is the best one) to be as close to the front as possible).
2. I like to put the "so what", the "human interest" first...to motivate interest. That is why I have a little bit of an essay and the discussion of economics/industry before the details of the electrochemistry.
3. I think we have enough other things wikilinked. I disdain having too many blue speed bumps. It takes away from reading text pleasantly. Don't go bluing anode and cathode, they are down in the technical para and we already have electrolysis blued. I mean you could practically blue every other word, but don't be crufty.
4. I will go add a citation for the market size to the chloralkali article (done).
5. Multi-para, bullets...it looks like I must be "breaking a rule". But really, just look the other way and let some innovation slip through. Gotta innovate the art form. Don't ask for permission, don't have a Wiki debate...just let some experiments move through. Maybe none of the crufty types notice. And much easier to beg forgiveness than permission (tm Grace Hopper).
