The conversation also touches upon the difficulty of attracting users and the need for a truly compelling differentiator beyond superficial customizations.
While HTTP/3 adoption is statistically significant, widespread client support is deceptive. Many clients only enable it opportunistically, often falling back to HTTP/1.1 due to middleboxes interfering with QUIC. This means real-world HTTP/3 usage is lower than reported, hindering developers' ability to rely on it and slowing down the transition. Further complicating matters, open-source tooling for debugging and developing with HTTP/3 severely lags behind, creating a significant barrier for practical adoption and making it challenging to identify and resolve issues related to the new protocol. This gap in tooling contributes to the "everywhere but nowhere" paradox of HTTP/3's current state.
Hacker News commenters largely agree with the article's premise that HTTP/3, while widely available, isn't widely used. Several point to issues hindering adoption, including middleboxes interfering with QUIC, broken implementations on both client and server sides, and a general lack of compelling reasons to upgrade for many sites. Some commenters mention specific problematic implementations, like Cloudflare's early issues and inconsistent browser support. The lack of readily available debugging tools for QUIC compared to HTTP/2 is also cited as a hurdle for developers. Others suggest the article overstates the issue, arguing that HTTP/3 adoption is progressing as expected for a relatively new protocol. A few commenters also mentioned the chicken-and-egg problem – widespread client support depends on server adoption, and vice-versa.
xlskubectl is a tool that allows users to manage their Kubernetes clusters using a spreadsheet interface.

HN commenters were largely unimpressed with OpenSpot, viewing it as a generic networking platform lacking a clear differentiator from LinkedIn. Several pointed out the difficulty of bootstrapping a social network, emphasizing the "chicken and egg" problem of attracting both talent and recruiters. Some questioned the value proposition, suggesting LinkedIn's flaws stem from its entrenched position, not its core concept. Others criticized the simplistic UI and generic design. A few commenters expressed a desire for alternative professional networking platforms but remained skeptical of OpenSpot's ability to gain traction. The prevailing sentiment was that OpenSpot didn't offer anything significantly new or compelling to draw users away from established platforms.
The Hacker News post "Show HN: LinkedIn sucks, so I built a better one" linking to heyopenspot.com generated a moderate amount of discussion, with several commenters expressing skepticism and raising concerns about the viability of the platform.
A recurring theme was the difficulty of bootstrapping a new social network. Commenters pointed out the "cold start" problem, where a lack of existing users discourages new users from joining. The network effect, where the value of a platform increases with the number of users, was also mentioned as a significant hurdle for OpenSpot to overcome. Several users questioned whether OpenSpot offered enough differentiation from LinkedIn to entice users to switch, especially given the established network and features LinkedIn provides.
Some commenters critiqued the site's design and functionality. One user pointed out the lack of infinite scroll, which is a common feature on modern social media sites, making browsing less seamless. Others questioned the value proposition of OpenSpot, suggesting that LinkedIn, despite its flaws, adequately serves the purpose of professional networking.
There was a discussion about the claim that "LinkedIn sucks." Some users agreed with this sentiment, citing issues with spam, irrelevant content, and a push towards gamification. Others argued that LinkedIn is a useful tool, particularly for job searching and recruitment, and that its perceived flaws are not significant enough to warrant a complete switch to a new platform.
A few commenters expressed interest in the platform and offered constructive feedback, suggesting features such as better search functionality and improved profile customization. However, the overall sentiment seemed to be one of cautious skepticism, with many commenters doubting OpenSpot's ability to compete with LinkedIn.
The founder of OpenSpot engaged with several comments, responding to criticisms and explaining the platform's goals and features. They emphasized the focus on genuine connections and the absence of algorithms and gamification, positioning OpenSpot as a more authentic alternative to LinkedIn. However, many commenters remained unconvinced, highlighting the challenges of competing with an established giant in the social networking space. Notably, no commenters expressed outright enthusiasm or a strong intention to switch to OpenSpot, primarily focusing on the hurdles the platform faces.
