Core Viewpoint - The discussion around the acquisition of Hupu is misguided, particularly in comparing it to Xiaohongshu, as it overlooks the impact of the era in which Hupu was established [1] Group 1: Historical Context of Hupu - Hupu was founded in 2004 as a vertical interest site, primarily focused on basketball, during a time when content platforms and communities were not yet conceptualized [2][3] - The internet in that era was characterized by a tool-oriented mindset, where users sought specific information quickly due to slow internet speeds [8][10] - Hupu's content specialization was appropriate for its time, as users expected clear categorization of content to find what they were interested in [7][12] Group 2: Challenges Faced by Hupu - Hupu, along with other vertical sites, faces significant challenges in the current era due to changing user expectations and the nature of content consumption [12][19] - The reliance on imported content from foreign leagues, such as the NBA, poses a risk, as fluctuations in these leagues can directly impact Hupu's relevance and user engagement [14][20] - Unlike platforms like Xiaohongshu, which are built on local user needs, Hupu's model is heavily dependent on external factors, making it vulnerable to market changes [19][21] Group 3: Comparative Analysis with Other Platforms - Other platforms like Bilibili have successfully transitioned from niche communities to broader content platforms, showcasing adaptability that Hupu has yet to achieve [27] - Hupu's situation is exacerbated by the decline of the NBA and CBA, which diminishes its core content offering and user interest [24] - The evolution of user engagement from a purpose-driven approach to a more casual browsing experience complicates Hupu's ability to retain its original audience [9][11]
