for example, my email is guest666@gmail.com, i want to use url plus.google.com/+guest666, but google won't allow me to do that, even when guest666 is available to be claim. They force me to use +(my name)
1. My name is "Firstname Lastname".
2. I've checked and for plus.google.com/+<URL>, both "FirstName" and "LastName" aren't used by anyone. Hell, even "FirstnameLastname" is not taken, or even the part of my first name which is my nickname let's call it "First" is free.
3. But Google wants me to have a stupid URL like plus.google.com/+FirstnameLastname<some stupid characters or numbers here>, just because some algorithm thinks "a lot of people might want that name".
Well, then fuck you Google!
IMHO they just want to shut-down G+ with little grace or sth.
