On android my browser refuses to go to the link without logging in and the G+ app says it can't handle the link (what is G+ for then?). This along with YouTube and sometimes Google groups demanding logging in is getting too much for me. I've already switched to Duck Duck Go for search. Now I'm in the market for a new email provider and docs are going to cloud storage.
