The best thing about the ability to call in your tweets is that now you can "live blog" activities that require full use of your typing fingers. People love to post Twitter updates of their adventures. Now you can send live, real-time Twitter updates while rock-climbing, jogging, fishing or flying a kite.

There are two downsides to posting Twitter tweets via voice call. The first is that reQall may occasionally mistranscribe your message. The service is very good, but sometimes doesn't get it right. Just inform your followers that you're sending tweets by voice call, and they'll forgive occasionally garbled tweets.

The second downside is that it can take between five and 45 minutes for your Tweet to appear because both reQall and TwitterFeed take some time to process, and TwitterFeed checks your RSS feed at a minimum frequency of every 30 minutes.

One final note: All these services -- Twitter, TwitterFeed and reQall -- come highly recommended even if you don't set them up for voice tweets. For example, reQall is an extremely powerful new voice-based productivity tool for those so inclined. Look at .
