Four conditions of Web 2.0

· Condition of Web 2.0 Part 1: Automation
· Condition 2 of Web 2.0: interactivity
· Condition 3 of Web 2.0: Lower the threshold
· Condition 4 of Web 2.0: Free

Last time about Web 2.0 "Ultimately, what is it, Web 2.0?I tried to give a specific example by saying that.

In this time I will memorize things like 'conditions' to be classified as such Web 2.0.
There are various opinions about the conditions, but in my opinion "automation" is the primary condition. Next is "interactivity" and "lowering the threshold". And the end is "free". I call it "Web 2.0" with all the services on the net containing these four items. Let's take a look at each condition below.

· Condition of Web 2.0 Part 1: Automation
Google patrols automatically and results are automatically arranged. Content-linked advertisements automatically decide the advertisement to analyze and display the contents of the page. Blogs will automatically format and display if you input characters. Comments and trackbacks are also displayed automatically. All other services categorized as Web 2.0 are also automated, automatically configured, automatically categorized, automatically generated, and so on.

Technically, we often use the following technologies / things.

AJAX(Ejika)
DHTML
Open Source

Based on these technologies based on technology, it is "Web 2.0" to provide various automated (fully automated, semiautomatic and slightly automatic) services.

· Condition 2 of Web 2.0: interactivity
It is what is called user participation type. For example, blogs can participate positively by watching people by commenting each article or sending a trackback. The most extreme case is where you can edit the page you are viewing freely. For example, the project "Wikipedia" (Wikipedia) that creates free encyclopedia.

Wikipedia

Wikipedia: Guidebook Writing - Wikipedia

Any item of Wikipedia can be added or deleted freely by clicking "Edit". In other words, you can actively change from here to say "write / edit / comment" as well as passive use of "one way to go and read", so that information sender Not only the reader and users can interact with each other, it is "Web 2.0" to provide such interactivity.

· Condition 3 of Web 2.0: Lower the threshold
No matter how much automated or fully automated technology is used, even if interactivity is ensured, unless it is easier to use, that is, if the threshold is not lowered it can not be called "Web 2.0".

For example, in the case of a blog, once you set it, you can update it by writing letters later. The point is that it can be renewed without specialized knowledge. If you twist the faucet, or just push the lever it will be as easy as water will come out.

Also, being able to perform intuitive operation also leads to lowering the threshold. The technology mentioned in the item "Automation", such as AJAX (Ejacut), has lowered the threshold of using the service by making it easy to operate. Let's compare the following two map sites.

A map site not using AJAX "MapFan Web"

The map site "A Google map" that uses AJAX

When moving on the map, "MapFan Web" clicks on the top, bottom, left and right edges, but for "Google map" you can move it by dragging with the mouse. In short, this is the essence of AJAX, a technology that makes net service available as a normal software.

As a result, using AJAX enables the following things.

"NexImage" which can process Photoshop grade images online - GIGAZINE

How to use Japanese version of free task management service "Remember The Milk" - GIGAZINE

Drag and drop AJAX folder tree - GIGAZINE

It is "Web 2.0" to provide service by further lowering the threshold by enabling software-like operation in this manner to lower the threshold and make it available without specialized knowledge.

· Condition 4 of Web 2.0: Free
By using the technology to automate, it is possible for users to create content that secures bidirectionality by themselves, and as a result, sites that always provide fresh content can be realized with lower maintenance cost than before.

For example, in the case of Wiki services, the viewer edits, so the service provider does not have to create content. Feeling to leave it to those who are looking. In addition, the content will inevitably be enriched if the number of visitors increases. With content-linked type advertisement, server maintenance fee etc. can also be created, so as a result, we can offer free service to users. If you provide it for free, the threshold is obviously lower.

Providing this service for free is also attributable to the fact that each open source software itself, which is the basis of various technologies supporting Web 2.0, is free. Besides the maintenance cost, the cost of development etc. is much lower than before, which is related to the fact that the number of participants increased and the sharing of knowledge about techniques advanced. Furthermore, blogs and wikis have become widespread, the advent of excellent search engines such as Google has made it possible to consolidate, share and sublimate these knowledge more than before. Web 2.0 itself creates Web 2.0 at a low cost.

In addition, this makes it possible to provide services that have been charged up to now, free of charge by using low-cost technology. On the contrary, what is supposed to be paid can be provided free of charge by advertisement, which is also "Web 2.0".

Especially, it is important that Web 2.0 which touched slightly further creates Web 2.0. By linking each service, convenience will increase further. It will not be completed by each service, and each will be able to do a lot more by cooperating via the net, this is the most breakthrough point of Web 2.0.

Looking at this way, all the concepts and features of Web 2.0 are gathered in Google and various services provided by Google.

Google's service

By using what you like from Google's services, you should be able to understand "Web 2.0" as a real experience.

The next time it is the last concept to understand Web 2.0, there are many elements that are fundamentally missing in the general Web 2.0 commentary, "Web 2.0 business modelI will explain about.
