Evernote is the key to organizing all of your ideas. You can store web clips, files, photos, music, recorded audio, and text notes into a single place. Evernote is a taggable and searchable database, and even allows you to search texts within an image.
So if you happen to be out at event, and take a picture of a business card, Evernote can search the text in the image, tag everything to make searches easier, and organize all of your ideas in the only notebook you'll ever need.
