What challenges/issues did Instagram and Pinterest face when using Django to build social networking sites?
Were there any other challenges they faced apart from scalability?
Another challenge was that Django uses SQL databases to store data, which can be limiting for social networking sites that need to store large amounts of data. Both Instagram and Pinterest had to find ways to work around this limitation to ensure that their platforms could handle the large amounts of images, videos, and user-generated content that people were sharing on their sites.
