Sometime in February our Retweet Button passed the 100,000 mark in website installs. We launched the Retweet Button back in February 2009 – so we have achieved this milestone in 12 months. We also peaked at 300 million retweet buttons served in one day (thanks to the iPad) and in the last 30 days we have served over 7 Billion buttons.

We are very proud to have some of the biggest brands on the internet using our services below are just a few of them.

Flash

I would also like to single out one company that has taken us into a whole new Arena, BREAK.COM worked with us to produce the very first Flash based Retweet Button, this has been a massive success for them increasing retweets by a factor of five. Look out for more innovation in this space.

New Functionality

To mark our milestone we are launching two really important bits of functionality that allow even more customization of the Tweets that are generated.

The first is HASHTAGS – we have long wanted to allow users to be able to tag each button so that users searching for relevant articles have a chance of finding them. You can now add one (or more) tags and we will automatically append them to the Tweet while still keeping within the 140 Character Limit. We are also pushing out an update today of our ever popular WordPress Plugin that adds automatic support for taking your WordPress TAGS and adding them to the Tweet Text.

Secondly we have added the ability to pre-allocate space at the end of the Tweet, it is a well known fact that Links get retweeted more when space is left at the end of the Tweet to then allow the next person to add the RT @[twitter_name] to the beginning, so from now on by default the Tweet will leave 19 characters, this can be overridden to give more or less space.

Both pieces of new functionality work on all our variants of the Button (Web, RSS, Mobile) and you can get all the details on HashTags and Tweet Space – or our main Button help page here.
