Professional people do professional things and go to professional websites

Slashdot: Information aggregation. Yes, aggregation. Because the information comes from a third party, its information is second-hand and non-instant. For example, I have seen all the information on the homepage today:
Hardware: computer mouse heading for extinction

Science: one of the coolest places in the universe

The BBC saw science yesterday: injections to replace heart surgery?

A long term concept and a precedent for success. Bbc2007 has a program. Vision of ure introduces this technology.

Therefore, professional people do professional things on professional websites, rather than looking at second-hand materials.

Every major should have its own professional website. For example, if a programmer pays attention to Java, he can pay attention to java.net. So what do you focus on?

However, Slashdot has its advantages in aggregation. Although it is slow, it is appropriate for non-professionals who do not have high requirements.
