Given the ubiquity of extremely well-engineered social media technology available at no cost to users I see frequently discussed, it might be useful to note:
- Twitter is 16 years old, raised nearly 13 billion USD in venture capital, employed thousands of engineers, and had a successful IPO. https://www.crunchbase.com/organization/twitter
- Block Party is four years old, raised nearly 5 million USD in seed dollars, and employs multiple people full-time. https://www.crunchbase.com/organization/block-party-4a94
Developing technology is not free.
