Google’s +1 is Google’s answer to the Like-it button on Facebook. “Liking” and “+1-ing” are widespread on the Web: almost every Web page has either a “Like it”, a “+1″ button, or both. However, Twitter is an exception to this: there is no explicit syntax available to express that a user likes a Tweet, a re-tweet is the closest the user has to express this sentiment.
Our ikangai science team started to work on Tweetflows a several months ago and we managed to publish a paper that explained the concept of Tweetflows on a scientific level. On of the main design goals was to create a language with a very flexible syntax of Tweetflows that can be read by humans and computer programs alike. For example, in Tweetflows, sentiments or recommendations can be expressed by a tweets like LG didLike.WebPage http://www.ikangai.com or SP @joahnnes2112 recommend.WebPage http://www.ikangai.com.
Given the somewhat cumbersome syntax of this, we investigated the use of a more concise syntax for this. Our solution is to adopt Google’s +1 to express a sentiment (liking) or a recommendation by introducing a new syntax element, the “+1″ prefix. Now, the example from above can be written as

+1 @joahnnes2112 http://www.ikangai.com

which is shorter and describes the fact that a user recommends the Web page http://www.ikangai.com to the user @johannes2112. If the user is omitted

+1 http://www.ikangai.com

then the tweet can be interpreted as “like”.
We continue to work on a syntax update of Tweetflows and investigate other constructs that can be shortended (e.g., provision of services (SP), logging of service acitvies).
