No, no, no, NO!!!11 I've had it with these "sea of floating text on an expanse of white" redesigns, seeing yet another one follow this mindless trend just disgusts me thoroughly. The lines, subtle gradients, and other affordances of the old design serve to organise and direct your eyes into the appropriate sections; without them, everything blends together into a jumbled mess and it almost looks like the stylesheet didn't load fully.
If you feel disoriented, give it a minute.
I've had to put up with such redesigns for literally years now (I don't remember when the trend started --- mid 2010s?) and I don't feel them getting any better --- and eventually get around to making a user stylesheet to make them look better than they used to.
In contrast to the article this is one of the very few redesigns of a site which I actually would like (not mine, previously discussed at https://news.ycombinator.com/item?id=17242367): https://pbs.twimg.com/media/De17PIKXUAE27W6.jpg:large
If you know someone at Github, send them a link to this article. Maybe someone there will like my ideas and eventually get to implement them
Hopefully not. "Don't make me get out the custom stylesheet editor..."
