That's a really hard question!
I'd follow #SteemSTEM with a bit, because they really do a good job with curation.
I'd try to upvote technology posts like programming and electronics, because even with SteemSTEM, they often go under-rewarded.
I'd continue to support artists and photographers. Artists and writers are surprisingly still under supported on here. Maybe I could get a group of curators to help with curating writers with that much SP.
I'd try to use it in some way to fund a group of developers to produce projects for the Steem blockchain. We need more things to help encourage curation. We also need more cool games.
Think I got enough things there to fully utilize all that delegation? TBH, with only a month, I would probably freak out a bit. The thing there that I wanna do the most is find out a way to be able to run a group of developers...but that would probably take a lot longer.
