Keeping an online notebook or progress diary

It occurs to me that if I want to get serious about making progress in my pole and aerial skills, I need to do a better job of taking and organizing notes on what I'm learning and working on. I do sometimes jot down some quick notes after a class, but I haven't really come up with a system for keeping these. Want to use something software-based, rather than a paper notebook, so I can include videos and photos. And so I can do text searches. Wondering what other folks do?
