We are currently running a study on the effects of adding additional information to SuggestBot’s recommendations. Participation in the study is voluntary. Should you wish to not participate in the study, or have questions or concerns, you can find contact information in the consent information sheet.

We have added information about the readership and quality of the suggested articles using a Low/Medium/High scale.  For readership the scale goes from Low  to High , while for quality the scale goes from Low  to High .

However the contact information in the consent information sheet is dead.
I never consented to be part of this "study".
