It would be cool to have a family tree version of that, and I completely missed that thread when it first came out (course I think it was right around when I was moving!) (amazing job to 358 for pulling all that data together WOW!).
I was trying to wrap my head around it, how would the parent/child thing work for situations like 176/229/1511?? 176 was my HS team, then I founded 229, and then founded 1511... so technically 176 is a parent, but is 1511 the child of 229 or 176??

I doubt I'm the only case like that these days...
