May I suggest an alternative solution of differentiating between KDE topics and personal topics? Then we could add a filter, same as we do for languages.

(I'm sure this will obviously lead to a debate on what is personal and what is not, so I guess that would need some defining, but at least it would please both people who like to read these things on the planet and those who would rather not, as I guess this is one where it's hard to find a compromise)

I think it needs to be more subtle. At least two layers for personal, also. Controversy free and controversy included. As anything, these categories would also need definition. But for example, political topics would fall under controversy for me, especially things like Trump, Brexit, etc. I am happy to read a fellow KDE developer cycling through Europe. But I want to avoid a fellow KDE developer's post about e.g. Brexit.

This ticket is for making the existing rules more visible, not a filter mechanism, though.

Okies, I created https://phabricator.kde.org/T12322, if someone who knows phab better than I do could link these properly (if wanted), please do so, thanks

Put a short paragraph about Planet in the content area before the posts to quickly explain where the visitors are; link to the "About ..." page.

I quite like this solution, but I'm not sure there is an easy way to create this About page. I will put this is my todo list ;)
