Currently using confluence as a giant note book, since I keep leaving knowledge behind with every employer as I move on, I have decided to make a very personal wiki about EE/FW. I might one day open up this information to peers and maybe even the public. I am also using Jira to look after any freelance work I do, and trying it out for tracking some personal projects. I am deliberately using workflows I am not using at work just so I can sandbox ideas and for personal edification.
