Plus writing seems to be less mechanical and more creative, which helps me get the juices flowing when I come up with a new idea.
Why do ideas have to be private? if you have an idea, you can be sure that you are probably not the only one who came up with them, so feel free to discuss openly.
there's nothing worse than being paranoid about keeping your ideas to yourself.
Think of this way, on the spectrum of loathing to loving your idea, they have to be on the top end and have either the resources or technical knowledge to execute, and now they have to pass you who has a hypothesis already and is looking for feedback. They don't know how much or what you've already gotten, so if they flat copy/paste based on what you've spoken to them about they could be heading off in a different direction. If that's the case they're not really competing with you because they're somewhere else in a different niche.
Is fantastic. I can't imagine not using it.
I use http://www.evernote.com/about/download/web_clipper.php and later add additional comments where needed.
I also use a pocket size Moleskine to keep ideas/thoughts/daily-journals. Some of my coworkers/friends refer to it as my Dr Jones journal.
I was actually thinking about building an app to deal with this. However, EverNote looks appealing and I should try it out . . .
If my "Active Projects" kanban swim lane has some space, I'll pull from the "Waiting" swim-lane.
This way I can schedule those ideas, if I have some time (shown by the swim-lanes on the Kanban Board)
Ideas die in a vacuum. Don't be the guy that retires with a notebook full of ideas that no one ever tried. Talk to people and develop your ideas. If it doesn't work, toss it and move on.
Google Wave of course is being shut down at some point, but it will carry on in some form: http://www.google.com/support/wave/bin/answer.py?answer=1083...
I'll probably move to Evernote or checkout some suggestions in this thread.
When ideas include sketches, I just draw it on a paper, and take a picture of the paper with evernote, and throw the paper away, that way I get the best of both worlds.
Then I write down everything else.
now i use a private github repo and have all ideas in one markdown file that's easily editable via github's web editor. i already spend a good amount of time in github for other projects, so this is pretty good for me.
I've also played around with Simplenote on iOS plus the mac software Notational Velocity. They sync nicely.
