The apps.kde.org website has already helped a lot by listing all KDE apps, and more recently, we also created a lot of kde.org/for websites that list some KDE apps for some niches that might be interested in some of our apps. But also publish a “This week in KDE apps” blog post that would cover all the news relating to first and third-party apps (e.g., new apps, updates, new app relevant APIs), and this would be community maintained with a process similar to this week in Matrix/GNOME/… where people write in a Matrix channel and a bot compile the relevant posts togethers. There is also a human factor; by making an app a first-party KDE app, the app received a lot of help from experimented KDE developers as part of the KDE review process and also during the entire life of the app.
