Twitter scheduling platform Buffer has just unveiled their newest update, which allows users to schedule tweets and retweets from Twitter.com.

With the new Buffer extension, users will be able to schedule their tweets and those they want to retweet for set times in the future, so they aren’t bombarding their followers with 10 messages in a row (which, trust me, can get really annoying, really fast).

The extension is currently available for Google Chrome, and can be downloaded here. A Firefox version is in the works, too.

Once installed, users will see a Buffer button next to the retweet button when they find a tweet they want to share. If clicked, the Buffer button will send that retweet to Buffer’s scheduling service, and it will be sent from that user’s account at a later time.

Buffer’s Twitter.com functionality also works for any tweet you pen yourself.

Users who want to share an article or multimedia using a tweet button on a website can also take advantage of Buffer. The new update means that there will be a “Buffer” button next to the “Tweet” button when you tweet a link from an external website, too.

Timing is everything on Twitter, so this update is a big one. Buffer optimizes the times your tweets go out so that more of your followers will see them – and you can improve this optimization by pairing Buffer with Tweriod to really fine-tune when the best time to tweet is for you.

And since Buffer now works on Twitter.com, there’s no need to visit a third-party site to schedule your tweets, once you’ve set up your Buffer account. After that, it’s just a matter of a single click and your tweet or retweet will be queued up for an optimal time later in the day.

The guys at Buffer have been hard at work for the past few months: prior to this update, they integrated with Tweriod, Vienna RSS, and Ifttt and launched an iPhone app as well as their very own Buffer button. And all this work is paying off. Earlier this week, Buffer announced that its users had Buffered over 10,000,000 updates since it launched – which equals out to just about 80,000 per day.
