Most irritating detail is the interaction where there is what looks like a select box (little down arrow and everything) but it expands when you hover over it after a small delay. The delay ends up being the most irritating thing because it is just enough time for me to accidentally click where the drop down used to be and is now a home button! It is small but this gets me every time and it is just such a gross usability fail. Maybe this is unfair but I have a hard time getting past it to give g+ a chance when my first explorations smacks me with an experience that is so poorly constructed and violates so many obvious usability best practices.
