Neat. I like the safe and stable feeling of permanence from a permalink, here.

Building on this, I see now permalinks could be challenging to integrate "perfectly" to PHIND's "Ask a followup question" value-add feature, because that feature depends upon the original query's model to provide "perfectly" (my word) useful "followup" results. And a permalink's model should be expected to quickly be stale, and quickly discarded, at this time.

I can conclude then, there is less value to permalinks at an app level, since the value-add features of the e.g. PHIND webapp may be compromised if they're intended to also work with the permalink data. And perhaps more value would comes from a trivial global, static history at the browser level instead of app.
