I'm thinking this: We keep our unchangeable usernames (kinda like twitter handles, even though those are changeable on twitter and not here) BUT we also get a spot to put a name if we want. You could put your username there too, or whatever you want for people like me with terrible usernames. You could switch it up with your mood but your username would be there too so people would still know who it is always. Would anyone like this?
It's just an idea. My username is dumb. :(
Yes, I would like to have a changeable name in addition to my username.
I think what we need more is a user search feature, and an instant chat. Would be nice to have a predicted tag feature, where as soon as you start tagging someone and you enter some letters you get suggestions for users whose names start with those letters. Does that make sense? It would make tagging so much easier because a lot of users have numbers and they are difficult to remember.
I usually try to pick a name that I will be happy with for a long time and I don't really like to change my name on social media sites. It's a little confusing and sometimes frustrating when someone repeatedly changes their name.
