LifeStreams -> WorkStreams

I love the idea of life streams - its great to be able to easily leave a trail behind you of cool stuff you have done/found.
I have been thinking lately about WorkStreams....
I used to be a lab scientist - and one of the things I used to hate the most about that job was having to maintain a Lab Notebook - it was a real drag having to take time out of my day to write (using a pen!!!) about what I had done. This is not to say that it wasn't neccessary, for patent and freedom to operate purposes it was essential, and it was really useful to have a record to look back on when I wanted to check something.
Nowerdays I am a software developer, and so the need to do this has subsided, I have all my code checked into Subversion , and that is all I need. However I really miss having that record of stuff that I have done/thought about etc.
For tagging cool web resources we have a tagging service, for recording my thoughts and ideas I have a personal twitter like service, and for recording the miscellaneous stuff that cant be put in our tagging service I have OneNote. However I really wish there was an aggregated stream of all this digital information that I could scan like my old lab notebook. A work stream could realise this, and not only that, if it was integrated into our Enterprise 2. suite, it would be effort free to create, but gives me that extra bit of return on taking the effort of tagging, and posting all this stuff in the first place, win-win.
