I think I've trained myself to keep most important issues rather shallow and funnelled through my email. So, that's the bottle neck. I do often think "Wow, I'm doing some data forensics on myself, ha!" as I try to search for whatever address or number that I need in the stream of the last 20 years.

I do feel like Google will nail down that for Gmail pretty soon. Having a conversational search instead of the old style search bar. So, I guess, if you can get yours working first you might be able to sell it to them in a couple years (or less).
