Regarding market stagnation,
sure the market has slowed down. Just a year ago we were expecting Intel Tejas core with well over 100Watt thermal dissipation. Now the focus has shifted towards power efficiency. Ofcourse thus reducing the "need" for water cooling. its been ages since tomshardware or anandtech etc reviewed watercooling products.
Regarding DIY.
Im still working on my little home made block, dremeling it was quite possible, just ive run out of interest for the moment. In part to the fact im hardly saving money infact DIYing a block costs more than buying a cheap ready made one which goes for as little as 19 €uro

Direction forward?:
I agree a more consumercentric site would increase the monthly hit count. Id also think more guides and how tos. If the wikki can be expanded that would be great too, maybe WC coling jargon dictionary etc. I love the interactive block charts, it be great to have a one klick kit comparison.
Personal reason for comming back?
The waterblock "charts"
the great DIY water block forum, (just love that shiny copper)
I can't say i have any valuable skills set that might help the site out. Might see if i have anything to contribute in the wikki. We all need todo our part. try anyway
