While actively browsing the internet (via phone/tablet/desktop), how can I quickly file an impromptu thought or idea into a centralized, searchable medium -- but importantly -- through a method that's as quick as possible and breaks flow as little as possible?
Ideally, it could be initiated through universal keyboard shortcut that brings up a pop-up box where you record the thought/idea, tags, and then have it disappear for later review.
The problem with the Evernote route is that it seems a bit "overkill" -- either having to create a new note for every idea, or breaking flow if you have to search for and pull up a note of centralized ideas. Notes would either quickly pile up with the former, or flow would be greatly susceptible to breaking with the latter.
With the individual note route, I'd be filing at least 15-20 of idea/thought a day. Having to review-sort 15-20+ individual notes each day, cutting and pasting each note's idea into a centralized/categorized document would be enough tedium to break the routine (in my case).
I've considered the route of using my GTD system for this -- Toodledo -- which I currently have a keyboard shortcut for through my Firefox browser, where I'm quickly able to pull up a to-do item, record it, and have it filed for review later.
What I worry about in doing this is the meshing of important tasks that need doing (centric to the GTD system) with items that are perhaps just scattered ideas, thoughts, or ramblings. I fear that it could infect the GTD system's effectiveness like an overwhelming virus.
With that being said -- I'm not opposed at all to answers that interact with this GTD system (like Toodledo and its browser plugin, for example), and in fact, it might be beneficial to have the two mind-dumping systems merged together.
