Twiddict is a web based Twitter client which allows you to tweet even when Twitter is down. It queues the tweets and posts them when Twitter is back up. A tool like Twiddict would have been very useful a few months ago when the Twitter Fail Whale was very common.
This is how Twiddict is described on the website:
We love Twitter. We hate when it’s down. If you’re addicted to Twitter as well, tweet your heart out through Twiddict and avoid life-changing withdrawal symptoms during Twitter downtime. We’ll make sure your tweets end up where they belong.
