Is this what you mean?
- connected: wikis that have some connection
- similar: wiki that have similar content
Yes, by "similar", we mean wiki where people talk about overlapping topics. For example, there's a lot of overlap between the robot wiki and the electronics wiki -- both talk about motors, batteries, ... etc.
When we say "connected by their WikiNodes", we mean that the WikiNode page on one wiki has a direct link to the WikiNode page on the other wiki. --DavidCary 10:05, 2 June 2006 (EDT)
