The ease of use, simple interface that makes it easy even with no technical knowledge at all! I can't think about anything in particular except how great this software is!! It's amazing what you guys have done here - keep up your good work :) We are solving problems related to accessibility by providing free access (open) datasets from various sources such as government agencies or private companies who do not want their information being made available publicly due to privacy concerns etc., which would otherwise be closed off if they were only accessible through paid subscription services like Datastreams/DataStreamXpress but now we're able make them freely usable without any restrictions whatsoever via our platform so everyone benefits.
