This problem, and I have experienced it too, and it's very persistent, is that the image uploader commonly freezes in mid-step for a good long time (up to a minute).
And then if you give up (who wouldn't, since it doesn't seem to be working?) it then either repeats the process, or randomly dumps the image into your text where it feels like, and on occasion in multiple locations, rather than where you want it.
I imagine this isn't a problem which will occur so frequently in the WordPress office as it does in the real wide world. Even if you work remotely, with your backroom access you almost certainly have better, more robust and more direct links to the servers with higher bandwidth than the average user enjoys.
I wonder if this might not explain the apparent wide disconnect in perception of the recent user experience here.
The scale of the recent problems is one issue. But the underestimation of their effect on users is quite another. Because out here, it really don't work that good.
There are danger signs that the patience of a loyal userbase is wearing thin just as the problems are slowly beginning to be solved. That's because two and a half weeks is a very long time in customer relations. Successful brands have been mortally damaged for less. Regrettably.
