Yes, it wasn't cool of me to cut them off at one sentence. Sorry.
Still though, instead of having a firm scour ALL your data, including things that you may not wish for others to discover, wouldn't it be better to let you choose what you want to be released after your death?
For example, besides marking select files/repositories, and setting my own criteria for releasing them (e.g. 1 year after I haven't logged on), I would have the option to notify specific individuals when my data is released, or even have it automatically posted on places like HN/Reddit/etc.
Other people would then have the choice of what to do with my data.
They could archive it, enshrine it, build upon it, whatever.
