#AcademicTwitter: if you get invited to edit a Special Issue at @MDPIOpenAccess journals, before you feel flattered and jump on it, consider this:
MDPI journals run *hundreds* of SIs per year.
They chose to flood the market for profit, and are using you to do it. Say no.
The IBES section of @AAEA_Economics is soo excited to finally join twitter! Follow us for updates on all things relevant to institutional and behavioral economics, for news highlighting our members, new work in the field, and relevant conferences/opportunities. #AAEA#EconTwitter
