Hey,
i think this forums needs to be seen as a general help channel. And myself as a user of ownCloud would never expect that an ownCloud developer is trying (or even being able) to pick out “real” bug reports within all the other general support / installation problems posted in this forums 
That’s why i personally think that issues (as it even got asked in Public links asking for user and password - #3 by mrow4a) belongs into the github issue tracker so that is guaranteed that these are getting noticed by some one of the ownCloud developers working on such issues and to avoid that information needs to be getting moved forward and backwards between both places.
But this is only my personal opinion as an ownCloud user, maybe some one of the ownCloud team as a different view on this topic and it could make sense to start a discussion with them in a new topic?
