After two years of Facebook and Instagram research work, we're excited to launch the fourth major ethnio release since 2009. Basically, we re-wrote every single line of code to allow you to recruit participants from any device.
We also just hit one million participants recruited for research, so big thanks to the team here at ethnio - Vitaly, Yulia, and Lindsey - for keeping things going with relatively little input, and another big thanks to our informal advisors to ethnio - Cyd Harrell, Jodi Leo, Mike Towber. With more participants coming through ethnio, there's also more design control over direct screeners to accomodate researchers that place ads on LinkedIn, Facebook, or Twitter to target researcher participants. On the tech side, we've upgraded to Rails 3.2.16 on Ruby 2.0, running on Nginx and Unicorn with PostgresSQL and are using a few cool things like Angular.js and Rails caching based on Redis. Please comment below or email us with any questions whatsoever.
