![]() Olson had just finished researching the site’s evolution when he zeroed in on the problem. Instead of serving as a portal to the site’s many subcategories, it spits out an aggregated list of the site’s most popular-and often most asinine-content. The project was born out of a common Reddit frustration: the impenetrable home page. >There is, Olson admits, an “enormous porn cluster.” If you like “engineering porn,” you might also like “Artisan videos,” “Ask Engineers,” “CNC,” “Machine porn,” and “metalworking.” Type in “Star Wars” and you’ll see other flourishing subreddits of a similar stripe: Batman, comic books, LEGO, Star Trek, cosplay. In other words-your guide to the vast Reddit universe. It’s an interactive map that taps into user posting patterns to surface subreddits you might be interested in. Zachary Neal and Randy Olson, two researchers from Michigan State University, to create Redditviz. So maybe my problem is just that I’ve never been able to find the places where the decent people hang out. The site had some 400 million unique visitors in 2012. The thing is, though, Reddit isn’t some obscure dive bar in a remote corner of the universe-it’s a huge watering hole at the very center of it. But, you know, one you still kinda want to hang out in occasionally.

Zachary Neal and Randy Olson, two researchers from Michigan State University, created Redditviz, an interactive map of the sprawling community. In summary, hard water may make your skin feel cleaner but leave your bathtub less clean, and soft water, though it may keep your bathtub shiny, may leave soap behind on your skin.Dr. (Take note, you may want to consider how much extra water you could be wasting by doing this.) Soft water doesn't create soap scum which is why some people prefer it over hard water to keep their bathtubs and appliances cleaner. After washing our skin we rinse the excess soap and scum off our hands and body, but how often do you rinse off your shower walls after using soap? A trick to help prevent scum buildup is to simply rinse your shower walls after showering or bathing. However, you may still be wondering why hard water tends to leave behind a white or gray residue on bathroom surfaces after interacting with soap? This residue is soap scum, formed when the minerals in hard water react with your soap. We’ve established that hard water does a good job of cleaning soap off our skin. So if you’re having trouble rinsing soap off your hands, you probably have soft water. On the other hand, soft water allows soap to lather more easily, and we can end up using too much - and if we have too much dissolved soap on our hands, it requires more water to wash it away. Additionally, if you use hard water, you may find it harder to get soap to lather up as you wash. Soap has a harder time binding with the ions in soft water, and it can actually cling to the slightly charged surface of your skin instead of being washed away. When this happens, we can end up with too much dissolved soap on our hands and it requires more water to wash it away. Hard water is actually much better at binding with the molecules in soap, allowing us to use less water to wash soap away, and making our skin feel “squeaky clean”. On the other hand, soap lathers more easily with soft water and we can easily end up using too much. If you use hard water, you may find it is harder to get soap to lather up as you wash. In soft water, these are replaced with concentrations of sodium or potassium ions. Water is said to be hard when it has a high concentration of calcium and magnesium ions. The terms "soft water" and " hard water" are important here. ![]()
