but still, the dot communism is a quote from some dude in the 90s, and wasn't the point of this particular article which was linked to. thanks for the obvious (which honestly, i had missed the reference).

The article goes into a lot of detail about how socialism is not the best term, but one of the better terms to use. The first half is devoted to syntax. Basically it goes through the levels of sharing, cooperation, collaboration, and collectivism and how really, it is a blend of socialism capitalism. I think relating it to how applying the free market to problems in the 90s resulted in huge progress, and now, we can do the same, with tons of people volunteering their time. For instance, 60,000 man-years went into Fedora 9, which would be unheard of in a big company. Anyways, ignore the language and focus on the themes. (and I apologize for not reading through all the responses).

I ran into this issue also since I have tons of pdfs and sometimes it can take a while to find that paper you remember that mentioned HylD or ZnO. I use the search client copernic http://www.copernic.com/ . It has a serious advantage over google desktop since it gives you this handy little preview pain which is useful when sorting through results. Since I carry everything around on a hard drive, I just have the program set to index that drive (which is set to always have the same drive letter). As for versions of the program, they kind of went in a bad direction with the 2.x releases and I kept using 1.6/1.7 for a while, but recently started using the current release, 3.x and it works like a champ. Good luck.

Tim has a good point in that most of these comments are over excitement about nanotech/nanotox. Granted you can point to author's affiliation with nano interest, but you can also point to other toxicologists interest at keeping the funding coming (which is unfortunate but a real phenomenon). TiO2, like many have said, is used in everything from toothpaste to cat food, and granted that isn't nano-scale, but still carries some of the same characteristics. Also, about those thinking this is going to create super bugs, its important to note that physical destruction of microorganisms is not something easily adapted to like antibiotics which target specific cellular processes. Personally, I have yet to hear of a bug that can live through a 10% bleach exposure(except for certain spores). This paper is a similar concept, and although this paint idea is nothing new, I think the greatest application of nanoTiO2 aside from photovoltaics, is using it as an immobilized film in water treatment parts, thereby killing microorganisms without the addition of those chemicals everyone hates. This of course would help us re-use our water, which is one the biggest overlooked challenges of the future of our country. And lastly, about people being all worried about its toxicity to humans, please keep in mind that anything can kill you in the right doses, so unless a study has some reference compound to judge it by, don't take toxicity to mean its bad. Hell, sand can be bad if its the right size and shape.
