Not impressive, there are zero-fee transactions sitting at 30+ hours estimated confirmation time.
Yes, the scale was impressive, of course.
Not impressive is that there were so many "large" transactions sent with no fee. Part of this problem is that major services (blockchain.info, I'm looking at you) that still default to zero fee. Oddly, blockchain.info has three options: (1) Frugal aka zero, with a warning that this shit will take forever; (2) Recommended fee by mainline client -- somehow, this selection still gets zero fee added, in the case of a txn worth (at the time) $1200 USD equivalent, and all cases AFAICT; and (3) Generous, 0.001 per txn.
Highly disappointed to have to discover this enroute. Luckily I sent to myself so I plan to sweep the keys and "doublespend" it -- but that's garbage.
