Meh, no point offering advice then. I never expected you to change anything, simply based on who I am, just don't pass it off as excellence.
Please don't play some "woe is me" bullcrap card here. That's not what's happening, you know it, I know it, and everyone reading this knows it.
I already fixed Volta, Chad, Nasser, Aral, and can now easily fix Sobradinho based on your commentary. I already sent Dachs a patch based on the first four. It is not a question of me ignoring and failing to act upon your criticisms.
It is a question of you making a broad and legitimate criticism (some dam-generated lakes should not be present) and then failing to take it to the specifics necessary for it to be actionable.
Yes, there are lots of dam-based lakes present that should not be. Here's the rub: their impact is minor, and I have already invested a few dozen hours in this project, and I have other things to do with my life. I do not really care about them. I never claimed it was perfect.
You, on the other hand, appear to care about them, enough to take the time to point some of them out. Great! Do that, and then I'll fix them, as I already have.
I can't be bothered to do the leg-work of identifying them myself. If you can't be bothered, then it won't get done, and you also have no legitimate right to complain. So do it, or don't.
