Connecting people with information.
On Clipmarks.com, you can see clips of text, images or video about all sorts of topics that other people find while surfing the web.
The idea is that through each other, we can learn more, know more and enjoy more than we could possibly do alone. As you find people who post clips that interest you, make them a Guide. Think of your Guides as a team of web editors you choose to consistently deliver you clips of things they find on the web.

Slashdot News for Nerds stuff that happens

The first thing you should know is that Fark.com isn't a Weblog. Fark.com, the Web site, is a news aggregator and an edited social networking news site. Every day Fark receives 2,000 or so news submissions from its readership.

Fark isn't an acronym. It doesn't mean anything. The idea was to have the word Fark come to symbolize news that is really Not News. Hence the slogan "It's not news, it's Fark." Fark was originally a word Drew became known for using online back in the early 1990s. He can't remember why, but his guess is that it was either to replace another F-word or that he was just drunk and mistyped something. He tells everyone it was the former since it's a better story that way.

Propeller is a social news portal, meaning that it is programmed by you – the audience. Our members post links to stories from all over the Web. Many of these stories originate from the websites of traditional media, including newspapers and magazines. But you will also find many stories that seldom pop up in the mainstream. Perhaps it does take a village – or at least a large community of news-hungry citizens – to nudge certain stories into the limelight.

The appearance of a story on Propeller is only the beginning. Once the link has been posted, you can vote on it, comment on it, share it with friends, or bookmark it to read later. In this context, news is not simply a pile of facts to be absorbed. It is a conversation. It is a process. And above all, it is fun: not a word we always associate with the news.

Way back in 2004, Manish and his wife, Asha, grew frustrated during the remodeling of their home. They found the process of sharing and discovering new products and retailers that matched their personal sense of taste and style difficult. As it stood, the online shopping platforms were weak and most sites just compiled product catalogs, leaving people to fend for themselves in a sea of information. Finding and keeping track of one's favorite products online and deciding what to buy was a painful and inefficient experience. So, in 2005, Manish and co-founders Keiron and Chetan, who both shared his vision of a new approach to online shopping, got together to transform the process into a more social and much simpler experience.
