What kind of websites are most promising?

The Web site webmaster's QQ group discussed "what kind of website has the most promising future (Qian tu)" for the third time. I presided over the discussion and participated with the webmasters. Summary.
What kind of website is the most promising? At any time, this is a concern for webmasters who want to start a business through the Internet and make the website a profitable machine, I will discuss my views with this discussion based on my own situation.
I officially entered the Internet industry in June 2003 as a salesman in a network company. At that time, the Internet was a bubble and there was no recovery. After half a year, I had the idea of deciding to quit, however, in the second month of entry into this industry, I became interested in technology. This is why I am still an Internet practitioner. In August 2004, my first personal website, A film, music, and animation website was born, that is, the current nmi. Cn's film, music, and animation channels were purely aimed at training technology and never thought about making money. The resources on this station were all leeching and closed in less than a year, in December of the same year, a meitui website for leg stockings was launched. Net (selfie pictures, CD, leg model appreciation, original style stockings) [download source code], the supervisors of the board of directors of a Hainan group (a listed company) do not make money, my management technology, this station has been running for a year, and it has also been closed, mainly because the VM provider has a limited access Volume. The access volume of such sites is very high, three months, there are more than 10 thousand registered members. I didn't expect to use the traffic to make money, and I don't know. In addition, I think this content is unhealthy. There are still many such sites, the deputy editor of TechWeb just created one.
In the next year until now, I have successively launched four websites, anyshop. Cn (shopping site), hnyp. Cn (Yellow Pages), nmi. Cn (website), goldtimes. Net (Information Station), now only the next three normal operations, from the initial training technology to seeking profit methods, I have been exploring, it is time to consider how to make money, I think it is necessary to analyze the types of websites that make money:
Category 1: Technical webmaster.
This kind of webmaster is characterized by technology, expertise in technology, and pursuit of technology.
Taking technology as the highest principle of the station, whenever there is a new technology in China and abroad, such webmasters must first know and learn it as quickly as possible, and then use it on their own stations for testing, this kind of webmaster is definitely a typical technology. A wide variety of technologies are used in the webmaster's hands, and most of these people are technical websites, due to limited human resources, all kinds of technologies are installed in your head all day. Of course, you are the first to choose a technology Station when making a website. The disadvantage of such webmasters is that they focus too much on technical applications, ignore the purpose of the station, what is the purpose of the station, and serve the user, ignoring the user's needs and blindly pursuing technology. It will surely lead to high and low. Of course, I will not consider how to make money. Of course, if this kind of webmaster is focused on promotion, the progress will also be very rapid. Hey, self-motivated!
Category 2: promotion webmaster, for example, Yang Zhiwu
