Thank you for the information! This is a gem of a database!
If you have the ability to buy a million Steem, I'm sure there are some people on the blockchain that would be very interested in talking with you. There are many projects going on right now that are looking for delegations, and partnership opportunities.
I'm by no means suggesting you shouldn't run a node. If that is something you have a passion, and an aptitude for, go for it, but I wouldn't limit yourself. Just the curation alone for an account with a million SP, is pretty juicy.
