User login from the perspective of interaction design

Whether or not "fully user-centered design" is a matter of great concern.
For "User Login", requiring users to log on is inconvenient and troublesome for user operations, however, if no user logon is required or long-term user experience is used to improve the process, it is not conducive to good information sharing and communication.

I remember writing it before.Google Personalized PK Windows Live, Recalling the discussion that GMAIL has just launched with friends,"If users are always driven out of their websites, the imagination of profit is very small! You need to keep the user on your website! To keep users on this platform, the first thing to do is to give them something of their own, so that they can be attached! Let them create their own "fun" here "...."

I think this is not just a demand for commercial purposes, but also a demand for deeper user experience.

I just saw Liu Ren say on the premise that user login is web2.0,"After a user logs in, 2.0 can analyze and track the user's preferences and show him the content and services that are closest to his previous preferences. The magic of 2.0 is that it is both large-scale and personalized."

I think what he actually wants to say is "user participation ".
Yes, "user login" is the basic "user participation.

• Recently, I was engaged in an interest exploration related to 2.0, where I encountered the following question: "Do you require users to log on? When a user does not log on, what percentage of tasks can he/she complete? When is it appropriate to require a user to log on ?"
  Frankly speaking, this is a headache:
  We are bound to go into a world of "information openness, information sharing, and information exchange". User login is a necessary foundation. We need users to "enter the room to communicate" rather than "freely wait and see everything at the door ".
• The user's operation process is a "stream ". We cannot give them a card at the source of the "stream, therefore, the user must be able to complete some of the information in the non-logon status. why does it happen? Why?
• When Can I interrupt a user's "stream" to allow the user to log on?
  In many cases, when we ask the user to complete the login task, it is more likely to be "bored" and "uncomfortable" to the user ".
  We can see that our current practice in many places is to interrupt the user's "stream" and ask the user to log on (even if you are upset, you will not refuse to do so for your purpose ).
  I think a better way is to make user login a natural component of "stream" by providing a user-friendly design for user login. (Oh, it's very casual. It's depressing to do it)

Another important concern is that:

1. An interesting discussion of this BLOG in the discussion group:
HI,

Note the following two issues:

1. The so-called logon here does not mean that you "enter the user name + enter the password, and the logon is successful .. in a broad sense, the user submits information to the system in many forms. For example, when you log on to many ASP forums, you will first be prompted to use cookies. In fact, this is a type of login.
2. The so-called "... ,.. Information communication is not just a conversation between users, but also between users and systems "..

======== 09:23:46 you wrote in your letter: ============

James's story is that the website did not log on, but provided practical and effective services.
"However, if you do not need to log on to the console or use the long-term user experience to improve the process, it is not conducive to good information sharing and communication. "You can say that, but it is not conducive to copying, promoting, and pulling money. We often hear about how many websites are ranked, how many users, and so on,
This "stream" is very good and necessary.

2. I received a text message on July 15, January 03, 2006.:
1860: "Traffic Department tip: This morning, a water leak accident occurs in the sewage pipe at the southeast corner of Jingguang Bridge in the East Third Ring Road. Traffic control is implemented near Chaoyang Road in Jingguang Bridge in the East Third Ring Road. Please take a detour. Thank you for your cooperation and support"

It fully demonstrates that sometimes "user logon" has some positive effects ~~ To tell the truth, I was so excited for a long time when I received the text message ,..

3. A friend gave such a reply to Liu Ren, and I liked it.:

James visited a weather query website. During his first visit, he was written with a COOKIE, and James left the website after checking the weather in Beijing.
