algorithm changes are aimed at improving the organic user's satisfaction
..... could be , but in my opinion they go hand in hand.
turning back to the relevance issue , something that strikes me about some of sites that have been mentioned is that they loose relevance signals as the content builds up. For example, in this thread , the fresh data get's indexed almost immediately , but as it get's older, and more pages are created with only pagination links, the heirarchy looses it's key indicators. Same for structures like Rand's site - although from memory the methods of ageing/ archiving pages is different. I wonder if those who have experienced similar losses have similar issues ( or indeed if it is correct ).
The concept may also be similar for folks who cannot get pages to serve results from day one. So on the one hand sites that grow , can loose relevance and on the other hand sites that create pages from scratch without all the relevancy indicators get ignored when too far removed without support from the root domain.
