What I was always sad about myself is that the imho more interesting bits of Klango such as the mediacatalogue, potential for games development etc never seemed to get used, what development was done was always on the community with sound avatars and more forum functions etc which to me were always least interesting parts of Klango.
I always wished the development had focused more on the unique things Klango could do as a platform, rather than the things you could get through other social networks and forums anyway.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
