TwitterNotes.com - Take Notes Using Twitter

Twitter is on its way to becoming the universal means of communicating quickly and directly with your acquaintances, so who's to say that you shouldn't make use of such an ubiquitous app for other reasons besides communication? This is exactly what the developers of TwitterNotes thought, and they have created an application that lets you take notes using Twitter whenever and wherever you're logged into your Twitter account. To take a note using TwitterNotes, simply start the message you're writing with a plus (+) sign, and the note will be saved to your Twitter account.

You can tag your notes in two ways, either by surrounding words in your note with asterisks, or by placing a cardinal sign at the end of your message followed by the words you which you want to tag to your note. For example, in the note, "Go buy *groceries* at the store today" #store, today", the tagged words would be "groceries", "store", and "today". You also have the option of writing private notes with TwitterNotes, but you'll need to access an external application called TNotes. From there, you simply log in to the service and they'll send you a message within five minutes to confirm. Then you can just send a direct message to TNotes every time you want to take a private note. All of the services are completely free and require no registration; simply use your Twitter account info to log in.
