i often use a dictaphone (an iphone app) to process my thoughts. it records your voice, like an answering machine message to yourself, and allows you to review and store your ideas.
i use mine 5-8 times a day.
i wish there was a way to upload those audio (.caf) files to blogger, so i could 'audio blog.' there must be. tumblr has a widget for that, and i've made use of it in the past (http://guerillahost.tumblr.com), but i wish blogger had easy access to one.
any help out there?
