I read this differently from quinn_sf, on substance rather than tone. Not convinced. The evidence being cited is consistent with the conclusion and also consistent with two other conclusions nobody has ruled out.

True, with the qualification that this is a self-selected group. The people for whom it did not work post less, and that shapes everything we think we know.

Bookmarking. The distinction being drawn above is the one nobody else makes. I will report back once I have actually tried it.

From the other side of the consultation, briefly. Start from the measurement rather than the conclusion. Almost every disagreement here turns out to be two people measuring different things and comparing the numbers anyway.

Same experience, arrived at from the opposite direction. The detail I would add is minor and it is already implied above.
