Wow! I just noticed that ipernity introduced a new feature: Different views of your homepage for different audiences, e.g. visitors (public), friends, family & friends and family. I haven't played around with this yet, but I guess the idea is - besides presenting your content in individual styles per audience - to have different default security levels for your content.
This is interesting. In any case: Team ipernity don't rest in giving us more and more features. In addition to refraining from any restrictions in controlling our content as is now effectively the case with flickr, the set of features is getting richer and richer.
Kudos to "iperniteers"!
