Picasa Web Albums and Google Drive

A few observations on PWA and Drive:

1. PWA: If you hide locations from viewers of an album and allow downloads, downloaded files seem to be stripped of location data - good! This wasn't the case in 2010. Hopefully it stays this way.
2. Drive: There is no way to allow non-Drive users to download entire folders, which seems like a very basic omission. http://productforums.google.com/d/topic/drive/-OCAzt9B0v8/discussion
3. Drive: Right now there seems to be a problem preventing people from even sharing folders with non-Drive users (error 500) http://productforums.google.com/d/topic/drive/G55YW9qnn2A/discussion
4. Google Groups are a mess. The URL is productforums.google.com, what's the difference between Groups and Google+, I can't find a way to bookmark/save/favourite topics (hence my posting them here), what's the difference between starred and favourites?
