usually that means looking at it, looking it up, figure out what, if anything i want to do with it.
i might delete it. i might archive it. i might bookmark it.
i might put it in my 8-mile-long notepad as 'idea: do this cool thing' so that i can find it later and see how bad of an idea it was, or on the very rare occasion, rethink thru it again, and/or even try to do something with it, bounce it off a friend, etc.
in the end, my two repositories are: notepad (which right now is 'Text' program on my Chromebook, backed by a google doc -- i.e. where the content/file actually lives) * gmail, just in my Archived email
i've never actually known the value of 'innovation management'.
always assumed it had more to do with PR -- "hey big company x, capture the _brilliant_ idea of your _brilliant_ people and make enough money next quarter that you won't get fired, or at a minimum you'll contribute to this idea of the company as being an egalitarian place, democracy, etc."
not hating, that's just my general impression.
