This blog is part of the "resume". When interviewers are hiring people now, they are likely to search the blogs left by candidates to make a pre-evaluation in advance.

If I am an interviewer and find that he has a high-quality blog, it can show his passion for technology. Secondly, the depth of some of his thinking shows that he is indeed thinking.

It is a process of knowledge accumulation for oneself, a place of solution record, and the most direct way to make friends in the circle.

Externally, this is the most direct way for others to understand you and share their own experiences.

A good technical blog is a good embodiment of a person's comprehensive ability, including summarizing ability, learning ability, writing ability, and persistence ability.
