I like it a lot. Feels like idle Wikipedia link surfing but with the key difference that each new step keeps track of the previous context. To me it is both novel and useful.
reminds me of the rabbit hole sessions I used to fall into in https://wiki.c2.com/ (a merge of the two interfaces (chat and context rabbit hole window thing) would be perfect for me)
For me, the snappy, easy to go from one link to another interface reminds me of hours and hours and hours spent browsing https://everything2.com in the earlier years of the Internet.
