I completely agree. This move goes against Google's supposed philosophy of controlled sharing within circles. Like many others, I use PicasaWeb as a backup and for organising my photos, choosing exactly who I would like to see them. I pay for the extra storage and have been very happy with it. Why on Earth would I want everybody that I tag in my photos for organisational purposes to be emailed about it, and then able to share my album with whoever he or she pleases? I also do not want others to have control of the tagging of my photographs, which I organise so meticulously. PicasaWeb was not a social network, and forcing it into becoming one renders it useless to all of the people who have used it for so many years. I thought that Google were going about + the right way up until now, but this is a disgrace.
