Reddit Scribe tree. ▪
FeedTree is a research project, and all research projects need data: preferably lots and lots of it. Each FeedTree node sends a small amount of anonymized data back to a statistics server; it’s enough to reconstruct the Scribe multicast trees that distribute new feed events. Since the FT network is still pretty small, these “trees” are usually more like sprouts, but I noticed this morning that the Reddit tree looked pretty interesting. So here’s a snapshot (PDF) of the current Scribe tree for the main Reddit RSS feed. As the size of the network increases, these trees (which are constructed organically as new subscribers join the group) will look more and more interesting.
