I first discovered this site while watching a btc sessions tutorial about a year and a half ago, and I still use it. When I first started looking for compatible channels I used the channel simulator function a lot. You can enter your public key or alias, and then simulate a channel with all the other nodes on the site, The circular graphics showing common channels is very helpful. I also use the node stats function to get an idea of where my node stands in the LN universe, and the visual charting capabilities are useful.

I also learned a lot just looking around the site. For instance, the glossary introduced me to concepts like centrality, betweeness, and other terms which I saw used everywhere but didn't understand.

I wonder if other SN members use this site, or did when they were first learning to manage their LN node?
