Web 2.0 site key to success

First, whether the site to meet the needs of more customers.
There's not a large absolute amount, according to circumstances. Flickr meet people such as sharing, image storage requirements, this is a very large crowd. Linkist and the establishment of a network of people to meet the demand, there is the need to have a lot of people. But you have to say an absolute quantity, it is estimated that the poor. In short, the Web site to be able to meet more of a user (or more) require. And that only a small circle of services, and Web 2.0 on the fundamental requirements of some of the gaps, not here.
Second, the Web site of the ease of use, the user experience is good enough.

A site for the masses, its ease of use is considered necessary. If your operating procedures, design features, such as to achieve too much too complex, will scare away customers. And a good user experience, users can continue to use your services and you are willing to contribute to information and resources is an important prerequisite. Therefore, the Web site operators, builders, it is a need to be fully taken into account. And this is also the birth of a new UI designer professional appearance.

This is mainly related to the user experience in several areas:

Connotations of the brand's image. (For example, google)
Whether the operation is simple. (Such as del.icio.us)
Whether or not functional enough. (Such as flickr)
Interface appearance. (Such as digg, last.fm)
The speed and stability. (Such as watercress)
Third, more resources, the quality and quantity.

Only when enough resources have been good enough, there will be more willing to join the user and therefore, Web 2.0 site of the original contents of the building is very crucial, but also beat his opponent out of imitators and driven into a tight place an important basis for .

IV site itself whether there is sufficient and sustained appeal.

Web site only if there is sufficient and sustained attraction, its management, is the development of stable and growing. In fact, to meet the above three factors, not a big problem.

External category
First, the number of users is enough.

The more the number of users to show more concern in some sites, sites that have greater potential to show how much influence these sites are registered users of the most important living resources. But we must also be noted that the volume of registered users on the Web 2.0 site's construction and development, is not the most important external causes. Active and able to contribute to resources and information the user is registered. As for how to allow the people to spare no effort to contribute to do is go to Web site operators need in-depth consideration of one of the issues.

Second, the user is willing to contribute resources for the Web site.

Users to create resources is the key to Web2.0 features. These resources are the Web site of the most important thing. They can take many forms: picture, audio, video, articles, and even relations. Any good Web 2.0 is able to fully mobilize the active users, for their continued contribution to the information and resources, this is a Web 2.0 site a critical success factor, or even can be said to be the top priority.

Free Web site for users to make contributions to the resources and information, there is a very important three points:

What is the user's own sense, the benefits.
User experience is good enough. (Such as user-friendly)
Web site will induce.
If Web 2.0 site can not be a good use of information and resources for users to create, then it just died, and so on. Do not blame the harsh reality, the fact is the case.

Additional information: the user why the voluntary contribution of free content to a Web site?

Expect to be around close friends look forward to being more concerned about the power of the people concerned about their secret on-line buried in a hole dug into the mood will become good (how many people think such an effective way?)
To show off their own or know of, or shared (most people do)
Academic exchange (few people do)
Google AdSense to earn money through the (very few people do)
SEO (indeed valid, but very few of the very few people do)
(via livid.cn) (via livid.cn)
Third, the site is well-known high enough

More people know your site and the services provided, then, that you need to target users of the Web site to provide the kind of service, they choose your site on the probability of significant increased. As a result, Web site so that the size of the power and potential, and enhanced a little bit.

To let more people know your Web site, mainly by word-of-mouth advertising and publicity:

Advertising: For example, eBay eBay and Taobao, the two sides are vigorously advertising, and its purpose is to let more people know that they are.And when these people have a need for the sale of goods, is naturally towards them.
Word-of-mouth publicity:

Media touted (on-line media, the gateway to promote the traditional TV, radio, paper media publicity, etc.).
he promotion of the user (if any of the viral marketing, Blogger's, to introduce users to friends, etc.).
