   Article: 20 min

   The article discusses the issue of disappearing social spaces and activities that are unpaid, such as gaming clubs for teenagers, visits to grandparents, and community clubs. It argues that these spaces are essential for social well-being but are not economically viable due to their positive externalities. The author suggests teaching the economy to recognize and value these unpaid activities by providing a basic income floor.

   • Disappearing social spaces due to lack of economic viability
   • Economy's inability to recognize positive externalities

   Discussion (231): 44 min

   The comment thread discusses the decline in third spaces for social interaction due to financialization and market-driven priorities. The main argument revolves around the need for alternative funding models, such as universal basic income (UBI), to support these community spaces. There is a mix of opinions on the role of markets versus regulations, with some advocating for UBI as a solution while others question its feasibility.

   • Volunteering is important for creating these rooms
   • The market doesn't prioritize the creation of these rooms
   • Regulations can prevent the creation of public goods like these rooms
   • Pension systems and financialization are pricing out third spaces

   Counterarguments:

   • These rooms are a priority for some people and could be funded through alternative means
   • The market might not always align with societal needs but it can still create value in other ways
   • Regulations that prevent public harm can sometimes disincentivize the creation of public goods
   • Financial systems have mechanisms to support social needs, such as UBI

10. So You Want to Define a Well-Known URI from mnot.net
    131 by ingve 13h ago | | |

    Article: 10 min

    An article discussing the proper use and considerations for defining Well-Known Uniform Resource Identifiers (URIs) in web protocols.

    Well-Known URIs can improve discoverability of site-wide resources, but may introduce complexity in multi-service deployments or when dealing with multiple publishers on a single site.

    • Well-Known URIs are best used when the client needs to discover information about a site efficiently.
    • Robots.txt is an example of where Well-Known URIs can be beneficial for discovering access policies.
    • Avoid using Well-Known URIs as URL shorteners or locking clients into 1:1 service-to-site relationships.
    • Consider discovery mechanisms and content metadata carefully, balancing convenience with granularity.

    Quality:
    The article provides clear guidelines and avoids sensational language.

    Discussion (84): 13 min

    The comment thread discusses various opinions on the .well-known URI system, its implementation issues, and alternative methods for achieving similar functionality. The debate centers around the necessity of specificity versus flexibility in web standards, with arguments made about ease of adoption, user experience, and the usefulness of certain features like domain verification.

    • The well-known URI system could be improved with more standardization and adoption.
    • Discord's use of a specific domain verification method is unnecessary.

    Counterarguments:

    • The current well-known URI system has its uses and is not without value.
    • Discord's method may be seen as a practical solution for their specific needs.
