Well, there's a reason it's not called Dude-terest. The latest darling of the up-and-coming social sharing space, Pinterest, has experienced rapid growth in both users and industry buzz in the last few months. If you had a sneaking suspicion that the majority of those users happen to be young females, you were right.

Pinterest's users are 80% women, according to recent data from Google Ad Planner, as presented by Ignite Social Media. The site is biggest among the 25-34 age range, followed by 35-to-44-year-olds. These site's popularity among people in their late 20s and early 30s is illustrated (quite literally) by the proliferation of images related to wedding planning and home decor.

The social Web is noisy. Each individual social network is noisy enough, but there's a second layer of noise - notifications - in which all the social apps compete with each other just to draw the user in. The creator of Handpick sent me along his solution today, and I love where it's going.

Handpick is a social Web app that doesn't interfere with the Web itself. It lives in your bookmarks bar or Chrome extensions. When you find a link you want to share, you click it, and it pops up a simple form for a title, link, description and a checklist of recipient groups you've created. When you click 'share,' it doesn't buzz all your friends' phones right away. It collects links for you all day and sends an email digest to each group in the evening.

Those of us who are still playing with Google Plus are eagerly awaiting its further integration into other Google services (in ways other than the red box in the top right corner). The updates are coming slowly but surely; Google Docs is now integrated with Hangouts, Google Maps can be shared as posts, and Plus posts are starting to appear in Google Web search.

But Google Plus is built around sharing, and one of Google's best sharing services is missing: Google Reader. It's the free RSS reader that lets anyone subscribe to any website's feed, and it's behind some of the most popular RSS client apps, like Feedly. But there's no built in way to share articles from Google Reader with your circles on Plus. Fortunately, you can make one pretty easily. Here's how.

A big problem for the nearly half a million apps available in the Apple App store is that they each lack an easily shareable social narrative that would empower users to buy.

San Francisco-based Kinetik, is trying to solve that problem and today launched an app-sharing application for the iPhone that looks at what your friends and potential friends are using and makes suggestions based on those apps to you.

Amidst all the hubbub about social media referrals this week, Google has finally made the +1 button useful. It now works the way we all thought it would, and it takes full advantage of Google Plus's rich formatting in posts.

Visitors can now share links to Web pages with their Google Plus circles by clicking +1. It opens a box for adding a comment, and it allows the reader to customize the snippet (also known as a +Snippet) of text and images that will appear in his or her stream. It also adds the option of in-line annotations, like Facebook Like buttons do, so you can see the names and faces of friends who have +1'd a page.

Forget Guitar Hero. Much more is possible in the world of musical gaming. Audiosurf has created what Alec Meer from PC Gamer UK calls "A near-religious musical gaming experience." It's a racing game that uses audio files of your choice to generate 3-D courses. The whole mood, even the speed of the ride, is determined by the songs you choose. You collect colored blocks that appear along the course as you go, and you compete online for the highest scores on the same songs.

Audiosurf employs user-generated content and both friendly and competitive online social layers. It's not just for racing; you can discover and share new music along the way.

That joke about how your smartphone can "even make phone calls" is pretty cliche by now. But it raises the question: why hasn't anyone done anything to improve the state of voice calls on smart phones? After all, we're carrying around powerful computers in our pockets, but the technology involved in phone calls on smart phones hasn't evolved much.

One company trying to change that is Thrutu, an application that adds real-time features to Android calls. For example, using Thrutu you can send money with PayPal from within a call, share and view a photo or "doodle" on a shared screen. It adds a number of possibilities for collaboration using mobile phones.

Today, Thrutu announced that an API that will enable developers to build new features or integrate existing applications with its platform. You can request access here. Use the reference code RWW1 for priority access.

The war that the record labels is waging to protect its copyrighted music is mistakenly believed to only concern services that explicitly allow you to share music.

That's not so true anymore. The RIAA is broadening its scope. According to The Hollywood Reporter, Its new targets are services such as Box.net, the subject of a subpoena this week in California, served by the RIAA's vice president of online piracy, Mark McDevitt. The RIAA seeks information about people it believes are using Box to illegally use "sound recordings."

In a prepared statement, Box.net said to The Hollywood Reporter:

Kassi is a service that enables users to share items, rides, etc. within a community. It's similar to several other services, such as NeighborGoods, Share Some Sugar and Freecycle. But with so many sharing sites, it's hard to figure out where to turn. If I wanted to borrow a power drill in Portland, I'd need to search each of these sites individually.

In a blog post at Sharable Kassi co-founder Juho Makkonen, proposed a common API that would enable users to search multiple sharing sites at once.

Editor's note: This is the first in a three-part series by Alex Korth on privacy. In the next post, he will cover problem areas that originate from provider goals and market mechanics.

To date, we witness the mass adoption of social networks. Roughly every 10th citizen of this planet uses these services to communicate with others. For the satisfaction of human need like socialization and self-esteem, users visit these services - very often more than daily. In communication, regardless of online or offline, people put their privacies at risk for some benefit.

In the offline world, we learned since our childhood how to do this properly with respect to the culture we live in. We learned how physics of the world around us work: We know when spoken word is recorded or who can see us communicating with someone. For most given communication situations, we perceive a level of transparency by sensoring the surroundings to control the receivers for what we want to say.
