The feedback for the new PI Square has been overwhelmingly negative (see the link below), and rightfully so. The excessive simplicity and minimalism of the new PI Square makes it hard to use and to look at. One of the comments from a moderator suggests that the new PI Square isn't even finished yet. Quality control got pushed aside in favour of agile development.

Also, many parts of the migration didn't work out so well, such as comment trees being flattened, long blog posts being truncated, and attachments being lost. Too much has gone wrong so far.

Before the new PI Square accumulates too much new content, please consider switching back to the old PI Square until the new PI Square is sufficiently improved. Either that or keep the old PI Square and apply the positive aspects of the new PI Square to it.
