This is one of them, a comment in response to a post in response to some of the fuss around the last change to the Update page.
Quoting rahaeli :
Yeah, but what you identify as a problem isn't the same as what we identify as a problem, honestly. The thing is? Our usability studies scare us. Badly. Our task-flow metrics terrify us. We have a higher task-flow abandonment rate than any other site anyone on the team has ever worked for. The percentage of people who, say, go to post to a community, can't figure it out, and give up and leave LJ (or just drift off, because they can't make the site do what they want it to do) rather than try to figure it out is terrifying.
Now if only they'd include those sorts of explanations in the announcements of the changes ...
