Love G+, it's been my main social network since the day it opened for the public (I wasn't lucky enough to get an early invite). That said, for the love of all that's holy, can we PLEASE get a better way to find an exact account when I plus someone's name. Even being able to plus their account number (or URL if they have one) would go a long way. It's a total crapshoot when I hit plus and start typing someone's name whether I'll find the account I'm looking for, and sometimes it's downright impossible.
For whatever reason, it's SLIGHTLY easier on mobile. When I'm on mobile and start typing a name, it seems to weight someone that's in my circles over the masses of other people. What I end up having to do, even though I'm sitting on a normal computer with the G+ website open, is picking up my phone, creating a private post there, just so I can interact with it on the main page. I find it sometimes completely impossible to get someone's exact account when using the website.
Now I know from a UI standpoint, UI experts must CRINGE at the thought of typing someone's full account number, but in a situation where there are multiple people with the same name, how is the system to know which John Smith I'm trying to create a private post for. At work (I'm an IT guy supporting people at GE) I run into the problem with multiple people with the same name ALL THE TIME (there are a ZILLION Ashish Guptas, for instance) and the only way I can get our systems to know I'm talking to one person over another is to use their unique SSO number. It's not elegant, but come on... you guys are engineers at heart, you can understand my desire sometimes for function over form.
