Goal
Currently, we promote a lot of famous KDE applications and applications that get a lot of big updates, but smaller applications that are considered "feature complete" don't get many updates and as such don't get any promotion at all from KDE promo. The goal is to raise awareness around these applications.
How
Post a weekly post on social media, featuring the application, with a small text of that, can be done with the application, a screenshot/video (depending on the effort/time we want to put in it), and a link to the project page in kde.org/applications. We shouldn't spend more than 15min on it and could probably prepare text and screenshots a long time in advance.
