There is a kind of contest right now, organised by Scaleway , and YunoHost is part of the "competitors" (well, we didn’t ask for anything but obviously they like YunoHost)
Scaleway is a new hosting provider which provides small SSD dedicated servers in 1-Click, with different "flavours" available. This way, for example, you can deploy a Gitlab, a Discourse or a Minecraft server at a glance.
So, they added YunoHost to this "incoming apps" list, included regarding their popularity. Do not hesistate to vote for the apps you like there:
