Since Panoramio moved to the US it became part of Google Maps which is part of Google GEO
There were people responsible for Panoramio and they were listed as the team on the Panoramio site. But they also were responsible for other applications within the GEO department and other members of the GEO department were working on Panoramio if necessary. Groups and this forum even depend on people from outside GEO, the same with the person who does the extra reviewing for the moderators..
From the ample communication we had with one Googler in the past year we could make up there´s still a group mainly responsible for PA. Who those team members are is not clear to us. Our main contact in that year claims he´s no longer member of the PA team. Since the last weeks we had contact with two more Googlers, one of them known to us as a (former?) team member, the other one unknown to me.
I don´t know who gave you the idea that there´s no team any more, we just didn´t know / do not know due to a lack on communication from Google side. We only know the two managers left and the list with members and former members was removed from the site.
There´s no way I (we?) can know what this means for the future of Panoramio. I can take an educated guess which way we are going, but that would only bring more speculations from others. As there are many users thinking that moderators speculations (guesses) are truth because they are more informed I will keep speculations for myself. Our information on that part is as good as yours at the moment.
I hope that more contacts will mean more communication with the team, any team. I for my part will gladly be part of that for the better good of Panoramios future.
