I just stumbled on this article on unclutter.com about various productivity tools that are available from various Twitter-Bots.  Below is just a few of them, but you really need to get on over to the Twitter Fan Wiki where there are hundreds all sorted out by platform and sub-application. 

It seems like each day I get more and more addicted to twitter.  It’s amazing how such a simple little application can be so useful!

• TwitterNotes- Let’s you take public (and private) fully taggable notes via twitter.
• Timer - Is a down and dirty egg-timer like application.
• Remember The Milk - Is a more sophisticated timer service should you need greater flexibility.

Did someone go out of their way to help you? Is a web site being particularly slow and flaky? Make your feelings known with plusplusbot. You can ++ (pronounced “plusplus”) or – (”minusminus”) anything. Think brownie points (but archived forever).

Of course the first thing you need is a twitter account.  If you don’t have twitter.. oh you just don’t know the addiction your missing!!!  So be sure to check that out first.

So basically how it works you ++ things you like and — things you don’t like (via twitter) and within a few minutes plusplusbot.com is updated with a score (and you’re scored as well with the total number of ++/– you’ve given).

Hmm.. we may have the answer to electronic political voting here!
