SurveyMonkey is no longer free. The company announced on Wednesday that it would be charging users for access to its surveys and tools, effective from May 1. The move comes as a response to the growing trend of people using survey-taking services for purposes other than research. The move is a significant change for SurveyMonkey, which was once one of the most popular survey-taking services around. But it’s not the first time the company has made changes to its pricing model. In February, it introduced a subscription fee for users who wanted to use its data analysis tools.
