Big dogs and small dogs barking together: An overview of mainstream Web 2.0 technologies

Chekhov said, "There are big dogs and small dogs, but the small dogs need not be disconcerted by the presence of the big ones. Both big dogs and small dogs bark - so they'd better bark with the voice that God gave them." In the former Internet, one could only see the big dogs barking and rarely hear the small dogs hum. Only with the advent of Web 2.0 were the natural online rights of the small dogs truly awakened, revealing an undeniable truth that has long been disrespected: the true masters of the Internet are the masses, not a few elites. And only in the era of Web 2.0 is every corner of the Internet a paradise for the small dogs, and every moment a festival for them.
