PS: When will #AcademicPublishers start to do this? For them, it would be all gain, no loss, whether or not their works were #OpenAccess.
I might not follow a #publisher, since too many of its works would fall outside my areas of interest. But I would definitely follow #journals and #book series. I'd also follow #tags.
