Enter HootSuite. With HootSuite, an individual or company now has the ability to track "buzz" about their brand or products. One great feature is the RSS/ATOM feed connector. If you currently have a blog and tweet about every blog post you make, then this feature will be very handy. Set the RSS/ATOM feed url and select the Twitter account that you want to use to tweet from. Every time a blog post is made, HootSuite will send a tweet from your Twitter account announcing it.
A great time saver. This feature can also be paused if you do not want to send tweets.
