I get that, and I find things like the demoscene interesting where the medium is a large part of the value -- but in this case (and most cases when stories like this are posted) it seems like a serious business product, where the medium is an implementation detail - the value is in other things like "open source" and "easy to install"
As mentioned, when I see "written in Scala", the implication is you ./sbt package it into a WAR, then stick it in a standard servlet container, and voila, up and running. In Gitbucket's case you don't even have to package it, just download the war.
So for a bunch of coders who may want to run a repo service on their internal network, employer or client's network, this is an interesting option.
Also it's FOSS, which I upvote by default here, be it from Mozilla or a random hobbyist.
PS - Not to bag on Gitorious, great FOSS project and much improved install as of late.
But yeah, anytime we have ease of install, we all win.
The story's title might indeed be more informative by stating that instead of focusing on the implementation language.
as a prospective user, having this web application up and running somewhere and showing it would be much more compelling to me.
I was actually evaluating different Scala frameworks and stumbled upon this project as well as another neat one: https://github.com/ornicar/lila
In the case of GitBucket the most important advantage is its easy installation, especially when compared to the more well known GitLab (that I never dared install after reading through the installation instructions).
For me it is :). I started to learn Scala after finding this nice project. Since it was so easy to install it (just copied the WAR file in a running Tomcat) it made me curious enough to give Scala a try and also to buy the Scalatra book too :).
It's quite possible that gitbucket is better than github or gitlab for some reason, and if so I'd like to know that reason; "It's identical on the surface and different under the hood (not necessarily better, just different)" doesn't seem like a particularly great way to generate interest...
