Utopian was recently hacked, so the automatic posting has been disabled temporarily.

The post you linked was a suggestions, suggestions are not posted to GitHub to prevent clogging the issues feed, but like you, I do agree it is weird to not show the project owner the suggestion.

When the utopian site goes back up when it is fixed, you can replace the post url with "utopian.io" and see the data on there, it shows the category and all. The site also allows you to see all the posts for one project, but the site recently went down because of a hack, and there is no estimated time of when it will come back.
