all good and valid points. As I said this is just my opinion, but I think having a unique design is important for distinguishing yourself from the crowd and does help boost the user base, it doesn't have to be beautifull, and of course it depends on the context and your goals. Maybe in this case, it doesn't matter at all if the design is the same as many other sites. Also though, unprofessional was maybe the wrong word, I guess more apt would be "project looking" or something related because I'm so accustomed to seeing github projects that use bootstrap to have a project page in no time.
