The Ultimate Collection of the Best Web 2.0 Sites Abroad

What Web 2.0 is, I think most people can't explain, but most are familiar with the term. I remember a long time ago someone asked me about it, and I didn't fully understand it either. I searched on Baidu many times, but still couldn't explain it clearly. Vaguely, I thought it was: the expansion of information resources through cloud computing, allowing for more diversity, with an emphasis on the exchange and interaction of information. If anyone wants to further understand this concept, I recommend checking out the detailed graphic article from "Possible Bar" about Web 2.0 (Illustrated Web 2.0 and the upcoming mainstream Web 3.0). By the way, I largely agree with the blogger from Possible Bar on many viewpoints, so I really like his blog. You should check it out when you have time. Today, we're only discussing foreign websites, not because I have any bias against domestic ones, but because foreign countries, as the pioneers of these ideas, better reflect the model and mechanisms of Web 2.0 websites. Therefore, the focus today will be on foreign websites. Moreover, most people are already familiar with domestic sites. However, this article will also provide a list of some major domestic Web 2.0 sites.
