[PW] I acknowledge what you say about other forums and the benefits you attribute to them, but can you please explain why you think this can’t happen inside this forum?

Given the complexities of modern web security, and the difficulty of presenting understandable and actionable information to users, new work would be most usefully presented in such forums, which can be done without being an existing member or needing to apply to be one.

[PW] Encryption and UI for website identity are very different. They require people with different skills. Identity UI requires product people and UX designers. We don’t need more engineers for this problem/solution. Right now we mostly have plumbers telling us why people are walking past our house without looking at it. They’re great plumbers, so they’re great at plumbing. They’re probably not the best people to tell us how to decorate our home though.

It is through efforts like WICG, which are used to house and build interest in nascent ideas for the Web that solve real problems for users and developers, that mature specifications are created and adopted.

[PW] I co-instigated the first ever W3C Incubator Group in 2006 [1] with Phil Archer. The WICG sounds extremely similar. Following a year of incubation, our project went onto a Full Recommendation Track, formally replacing PICS in 2009 [2]. Our Recommendation was never adopted, for numerous reasons, even though it had support from some browser vendors and other major potential implementors. Some browser vendors still use PICS today.

It has already developed a number of guidelines on the more intuitive display of secure sites to Internet users. These guidelines, which have evolved through rigorous and peer-reviewed usability research, and combined with the deep technical expertise involved in how modern Web security works, reflect a number of the industry best practices.

This approach, where the problem to be solved is clearly explained first <https://www.w3.org/blog/2015/07/wicg/#what-s-the-process->, has been highly successful for collaborations on evolving the Web, and is the core approach for most modern Web standards work. This process helps ensure the problem is well understood and can bring to light any faulty assumptions or premises, which is key to assessing how well different options addressing them might work.

[PW] I’m pretty confident that almost everyone who needs to be involved, knows what the problem is.

I’m happy to write a problem statement and a proposed solution to get something started. I’ve contributed to a lot of W3C initiatives and specifications and I still think this forum is the most suitable place for this particular work. This forum was started and built to address Internet Security from the perspective of encryption and identity. 

As a side note, how do you feel about the lack of privacy for visitors of the W3C Incubator Community Group Charter URI? [3]

You can learn more about the process of making and evolving proposals with the WICG here <https://www.w3.org/blog/2015/07/wicg/>.

[PW] We could easily put together a small team of respected independent industry experts from various stakeholders to help manage the project.
