It looks like Qondio has finally shut down.
I was a user of it from the early days when it was known as Qassia. I think it started on a fairly optimistic note as a place where quality content could be posted, and quality was ensured by a process of having other members rate contributions. Unfortunately being open access they had a lot of problems when some scammers moved in and tried to rig the voting process. If I recall correctly this led to them making some changes but by then the damage to their reputation seems to have been done.
It limped along for a couple of years and I noticed a week or two back that it no longer seemed to be there. For a while the domain name redirected and now seems to be on a hosting provider's default page.
I liked the idea and for quite a while I hoped it would recover, but alas it seems not.
I'm now working on transferring the posting that were unique to Qondio to this blog (or in a few cases one of my other ones) and will be keeping the original posting dates.
