TLDR; Kallithea is a great GPL replacement for GitHub, but you'd be hard-pressed to find that out on
directory.fsf.org
With the news of GitHub being bought by Microsoft, I decided to search the directory for alternative git based version control hosting projects (e.g. Kallithea). Unfortunately, there is no easy (pre-defined) way to do so. Actually, there isn't even help content to guide a user through the use of Special:Browse or Semantic searching using the tagset and ontology implemented at the Directory. Instead 'Help' just links off to the Semantic MediaWiki website for generic information.
What's more, when I went to the Special Page [1] where you can run a query based on license; and I selected all the GPL AGPL options; I get an error that the site doesn't allow that many parameters. [2]
And one last issue. It's almost impossible to see and copy that error message because it's hidden in a tooltip controlled by an onmouseover event. The only thing visible to the user is a tiny icon.
