The amount of projects using Hosted Weblate grows every month so it seems like there is quite interest in that. This growth will however bring some challenges in the future.
Currently everything is managed by myself and that really does not scale well. There should be some automation in the process of adding new projects and there should be more control given to project admins, so that they can change some things on them own. This is quite some coding, but there is another Hackweek on the way, so my plan is to implement at least something in this area as well.
Other side is unsurprisingly money - even though I just got new hardware to run this service (which will be hopefully deployed in a month or so), in the long term it might need other investments as well. That's why I've rewritten the donation page for Weblate and added some more options.
Most importantly the goal is now to get some regular income which would allow sustainable development of both Weblate and free hosting service. I think Gittip is great service for such goal, so let's see how it works.
