Yep! What Dave said.
Even in the early days of Packet Cluster the DX might hit the southern OH cluster, then the the eastern PA cluster, then the TN cluster and on and on - localized clusters of maybe 10 - 30 ops. At 3-5 QSOs/minute one could still keep the pileups manageable. Once the Internet became involved, bedlam ensued!
Back to the topic of funding....
We may be approaching a point of donation burnout. Yes, DXpeditions to the rarest and most remote places need dollars - lots. Unfortunately, it's getting to where, now, anyone going anywhere wants donations. QSLing is becoming more and more convoluted as DXpeditions try innovative ideas in an effort to recoup costs. (That's not all bad but there's a lot of inconsistency right now.) I think it may bode better for future donations if more expeditions were more upfront about why such and such trip is going to cost $n. A public budget sheet listing every minute detail isn't necessary but just posting a dollar figure really doesn't cut it anymore. People want to know that their hard earned bucks are going to be spent wisely and not on frivolous extras.
