Sorry if you are confused with the title, Is there any wordpress plugin based on Ajax which provide option for visitors to rate the post using impression voting such as "LOL", "WTF", "Brilliant" or anything and then count the voting afterward. Real examples can be found here: http://www.queerty.com/can-we-pleas...-actually-want-to-indoctrinate-kids-20110512/ or http://fairyfish.net/2011/05/13/new-google-analytics-trackpageloadtime/ you can scroll both articles until the end and will be a voting to choose (words on first site, and green emoticon image for second one). Thanks
