To survive by running open access journal is really difficult! My saving is gone, now. I can declare my bankruptcy, now, due to open access journals listed at http://www.mdpi.org.
Hope my colleagues do not go around to claim OA victory. It is a cause to devote your time and money. I am going to adopt "Open Choice". Not paid papers are not open access. Only paid subscribers can access. This will be announced in MDPI journals next month.
