This is a service that will be more or less interesting according to your degree of attachment to Twitter, but I think that mostly everybody will agree it is a novel application, and one which holds some potential.
In a nutshell, Current.im gives you the chance to keep a Twitter diary. That is, you are allowed to make entries that have to observe the famed 140-character length that has characterized Twitter from the very beginning.
The idea is clearly to encourage users to focus on these things that are really important, instead of coming up with rambling entries that never dwell on anything for more than a line or two.
Current.im is a free service. If you want to try it out, you will simply have to create an account by providing some basic personal information and by specifying your timezone. Once that has been dealt with, you will be able to start chronicling your daily life one micro message at a time.
Current.im In Their Own Words
Your private, daily diary using just 140 characters.
Why Current.im It Might Be A Killer
Because it will let you focus on these things that really matter when weighing up all the things that happen to you in your daily life.
