gunna add another BTC into this. Doesn't this have the potential to be really huge?
Yes. The only scenario that takes market share away from dark will be if bitcoin implements CoinJoin directly, which according to the thread is a long ways off (if it ever even happens). This coin shines even brighter (or darkens even darker if we keep with the theme) when you look at the hashing functions and the quicker block times compared to bitcoin.
That said, all the technology for this coin is still in alpha (or doesn't exist) and is closed source at the moment. Buy at your own risk, YMMV.
When I got into bitcoin I told my grandfather that no matter what, there was a black market that operated within its confines and would continue to do so, even if a white market never developed, thus preserving/increasing it's value (barring catastrophic outcomes). I'm thinking the same thing will happen with darkcoin. That said, I hope, as I did with bitcoin, that a larger white market develops.
The black market NEEDS darkcoin, the white market WANTS it. So far, so good.

Given the variable block rewards, is there any way to know how many DRK have been mined to date? I'm watching the dumping on the exchanges at anywhere near 0.002 and there's no way it can be mine-to-dump. There are only 13,248 being mined per day at the current diff / reward, yet people are dumping hundreds and thousands at a time. Much of it must be early miners or buyers who have the attention span of a goldfish, and I'm curious how many of them can be left at the current turnover rate.
coinmarketcap says: 3,403,074 DRK
However, I would much rather see the non-shiny version of the coin. The shiny one doesn't look so good when it's small and is too much in my opinion at any size
