This could be waaay better than Launchpad. And much nicer looking, too.
The site has promised nothing new that I can see.. Launchpad already offers what is currently being promised.
In addition, the launchpad build infra is well designed and provides an assured build that is using the same architecutrure as builds for Ubuntu's primary archive (including gpg and network isolated build hosts)
Launchpad also has a receipe based build process, that (I haven't tried) could surely tie into Github?
On the face of it, this seems like a fun project for the developers, but nothing new.
That said, I hate it. I can't stand the UI, it's not that it's "ugly" (which it is), but that it's really not functional. Things are just hard to find and others don't work the way I expect them to.
Plus, it has a lot of 'missing features' I now expect because of things like GitHub like tagging issues, naming Bugs as "Issues" because I like that everything (anything really) is reported like a todo list (not just 'bugs' in the regular meaning of the word) and other things.
Not an Ubuntu hater here, just someone that hates stale software.
