Scoble reported on ZapTXT originally as a service that can send RSS feed items via SMS, however, it does much more:
- Salesforce.com integration (CRM application)
- Craigslist integration — notification of items for sale, events, etc.
- Community/group messaging via SMS
- All kinds of other reminders and pre-defined tasks
Oh, and you can choose SMS or e-mail or both as your delivery method.
