"Allowing WordPress users the ability to delete revisions would save disk space and the planet"
I'm 60 y.o. and have been using computers since 1978. My first computer had duel 360k floppy drives and 512k of RAM.
I just can't get used to the extravagant waste of HD space that goes on these days.
It really bothers me that revisions are extended to 25 copies. I can't think of a single instance where I have had to use an earlier revision.
When I revise a page or post, that's the final word! Period!
Then there's the environmental issue. Collectively, servers use a lot of energy.
I'm not a "tree-hugger" wacko. I love technology. Let's just use reason here.
