Quora's success led to a lively discussion of the question-and-answer website. And the biggest difference between the traditional question and answer website, such as Yahoo knowledge question and answer, besides the change of interactive form, the most important thing is the quality of the person and answer. The more people with a professional background and the higher the participation, the more valuable it is for the question and answer website. The hardest part about such websites is how to attract professionals from scratch. So the form is better suited to organizations that already have a large user base, like TED.

TED conversations.

The nonprofit TED conference has been in place for more than 26 years, and has developed a lot of related awards, forums, affiliate programs ... Of course, there are many passionate professionals. Ted Conversations, a platform like Quora, has recently been released, with a monthly subscriber count of 15 million. Hans Rosling, a professor of global public health in Sweden, is the most active in TED conversations, the marketing guru Gaoting and the author of Runaway, Kevin Kelly, are also active users.

TED conversations has two notable features:

Topic classification, all topics are divided into three categories: "Ideas (Ideas), Issues (Questions) and debate (debates)"

Time limits, the topics in TED conversations are open time limits and can only be viewed after they expire.

On the reason for the topic classification, June Cohens said in an interview with TNW that some dialogues and ideas have different frameworks and models, some need to be debated, and some just ask questions. Different classifications actually reflect the way we respond to different kinds of thinking. For users, some people like to debate, some prefer brainstorming.

The opening hours are based on the advice of Clay Shirky, the author of the book "The Future is wet." Each TED speech is 18 minutes long, so time constraints take into account the echoes of the form of speech. In addition, they argue that most TED readers have limited time and want to use time limits to motivate participants to contribute the best answer. The time limit can also arouse more people's interest, as if the limited-term group buying site Gilt Group is also the success of this feature. Once the problem is turned off, it is automatically archived as "Reading Mode", automatically transforming active discussions into valuable content within the community.

TED conversations future development plans include:

Adding interactivity, adding emails, reminders, adding friends, or specific topics can enhance participation and integrate Facebook and Twitter.

Multi-lingual support, Ted's readers around the world, many volunteers are actively translating TED talks, such as the domestic Tedtochina. TED conversations will also provide multi-lingual support within one months.

Geographical location, geographical location tag is also a direction. But TED conversations geography shows the topic content rather than the user location. So if you're talking about New York, Lima, and so on, it's easier to use local labels.

StackOverflow: Content focused, powerful "tag", answer rate

StackOverflow, a new york-based start-up company affiliated with Stack Exchange, is a programmer-specific Web site that captures opportunities in niche markets, accumulates 760,000 of users, and reaches 16.6 million independent visitors last year.

StackOverflow CEO Joel Spolsky has said that high quality content and reasonable vertical classification are its key success factors. The current StackOverflow response rate is 80%. Community managers and members can close or revise questions by voting to ensure that the problem is clearly articulated. The person who answered may also get the corresponding points.

StackOverflow and Quora allow users to follow with each other, but it also allows users to not use real names. StackOverflow is currently making a profit through advertising, but wants to develop more profitable channels, such as using these resources to provide programmers with job search and part-time jobs.

INBOXQ: Close integration with Twitter, browser plugin

INBOXQ was founded in 2009, is the Y Combinator investment start-up company Answerly Products, as a browser plug-in launch. Currently only supports Chrome browser, will soon support Firefox.

INBOXQ's launch is based on two points. The first is that people like to ask questions on Twitter, but most people find it hard to get a satisfying answer. Second, many companies want to find customers on Twitter, but find it hard to get involved, and Twitter searches often return to unrelated results. So it can be said that INBOXQ's commercial objectives are clearer.

You can set the keyword, INBOXQ through natural language search to filter out the related problems, you can always see the concerns, and then share the answer.

The question and answer now looks more like a SNS element that can be blended into different social networks to derive different variants. However, regardless of the change, the level of participation and community quality are at the heart of the core, which determines whether the interaction of questions and answers is of value to the user. With the participation of professional communities such as TED and Staroverflow, the Quora advantage will become smaller and more competitive.
