The following points give me an uncertain feeling about the future of Tagadelic:
- All open issues have been closed with "won't fix"
- The issue queue has been removed from the project page
- The module has been marked as "Maintenance fixes only"
- People are being asked to use Github rather than drupal.org
This gives me the impression that the interest in maintaining and further developing the module has diminished. If it is a problem of resources, and you do not have the time to maintain it, isn't it a good idea to post an open invite for co-maintainership? Someone might be willing to step forward and help out.
I could be mistaken though and perhaps you just prefer Github over Drupal.org and I have nothing to worry about. If this is the case then feel free to mark this as "Won't fix" :)
