“Starting today, we’re rolling out an email notification that lets you know if someone you follow retweets or favorites one of your tweets” Twitter tweeted yesterday.

Twitter aims to build on the popularity it has enjoyed in part from the warm fuzzy feeling generated when yet another Twitter user signs up to “follow” you, even if you hardly ever tweet, by adding the new email notification. It is not yet known whether it will be possible to opt out of the notifications.

For Twitter users that tweet at least occasionally, especially those with a large number of followers or the rich and famous, the new service will be appreciated.  The aim of the new email notification feature is to expand on the functionality of micro-blogging and build its appeal by giving members the satisfaction of knowing when someone has valued their thoughts or opinions enough to retweet or favorite the tweet that contained them.

Twitter currently boasts 300 million active users and logs 13 billion API requests every day, and according to a report in The Next Web, the number of tweets increased 41 percent in the first three months of 2011.
