LifeDigger is a personal knowledge database, where you can write about everything you learn or see in your work / interests. The main purpose of LD is not to end up with 5000 static notes that you will never see again but more to be able to easily search and review notes. LD tries to make it easy for you to build an actual knowledge of your notes.
