Hi Luis! If you compare include/exclude to a rank list, I guess the pinned/blocked would be the equivalent? In these "super lenses", I think that at least region setting should be an option.
In practice, a user would create a lens as normal to start with, and then start upranking and downranking domains as she prefers, to serve the purpose of the lens. Without these rankings having any effect on her normal search results.
Luis Some intial thoughts: I imagine it to be part of SERP and work similarly to adding songs to a playlist. Additionally, we would need to build some sort of algorithm to prevent bad actors from spoiling these super lenses, if editing is open to everyone.
I expressed myself in a confusing way. By "public" I don't mean that anybody can edit the lenses, but that everybody can use it. The creator will still own it. Then, in the case of very good lenses, Kagi can fork it and make it "official". Meaning that the Kagi team would be admins of the official lens, and the original creator would keep their lens.
For certain subject matters, I could even see Kagi having official lenses that differ between regions and languages. To take an example that many people use a search engine for: looking up pharmaceuticals. These have different names in different languages, and different legal status and recommendations depending on region. Here, it would be very useful if super lenses had different rank lists depending on region, as long as there is such a lens made of good quality.
If we take the current demographic of Kagi users, I think they would in no time make high quality lenses for things such as foss.kagi.com , archlinux.kagi.com or python.kagi.com
A later feature could be that the standard Kagi search will suggest lenses in an unobtrusive way to normal users, based on keywords they've used in their search. Maybe as a button to apply a super lens to their current search, without the user having to add the lens to their list.
As for initial discoverability, maybe just a list where user created super lenses gets added automatically and a ranking based on "new / most used" and a list for the official super lenses also. With the risk and probability that controversial user created lenses will be in that non-official list.
