This study investigates whether two microblogging  platforms differ in the terms of use of Netspeak based on the total number of instances of Netspeak, focusing on three chosen Netspeak features. The focus lies on abbreviations, emoticons and orthographic features. The two microblogging platform sites are Twitter and Tumblr. Posts with a total of 1500 words from each  microblogging platform were selected on the same day in order to find and analyze the Netspeak features. The analysis of the Netspeak indicates that Twitter has a larger number of instances of Netspeak than Tumblr. However, when comparing the total number of instances of the specific features from Twitter and the total number of instances of the specific features from Tumblr, there is no major difference between the two microblogging platforms.
