Like it? Tweet it!

"Like it? Tweet it!" is a jQuery-powered JavaScript widget that enables visitors to your website or blog to write a tweet about the site directly in a box displayed in the corner of the website, with a link to the site already embedded in the input field. The widget is a unique opportunity for site owners because it makes it easy for users to share your site with friends while still giving them the opportunity to type out something cool for themselves and thus avoiding auto-tweets

"Welcome to TweetUp - home of the world's best tweeters! We've embarked on an exciting quest to let even more people realize the tremendous potential of Twitter as a real-time information network. TweetUp makes Twitter more relevant for everyone. It's the fastest and easiest way for you to find the best tweets and tweeters in the world, and for serious tweeters to grow a highly targeted following. One of the biggest complaints about Twitter is that 80% of tweets are pure noise, while valuable tweets fly by in an instant never to be seen again. All of which makes finding useful information from the most important tweeters almost impossible. And for serious tweeters, there is the daunting task of attracting interested and relevant followers. TweetUp aims to change all of that. TweetUp boosts the world's best tweeters on any topic to the top of search results, raising them above the noise and giving them persistence against the backdrop of millions of tweets that fly by each minute"

Twitter acquires Cloudhopper

Fromm the Twitter bog: "Twitter was inspired by SMS and we continue to embrace this simple but ubiquitous technology. In fact, Twitter's 140 character limit was designed specifically to allow for any tweet to be read in its entirety whether you're using a rudimentary mobile phone, or a more sophisticated Internet enabled device. Over the last eight months we have been working with a startup called Cloudhopper to become one of the highest volume SMS programs in the world - Twitter processes close to a billion SMS tweets per month and that number is growing around the world from Indonesia to Australia, the UK, the US, and beyond. To help us further grow and scale our SMS service, we are happy to announce the acquisition of Cloudhopper, a messaging infrastructure company that enables Twitter to connect directly to mobile carrier networks in countries all over the planet"
