Well, I don't think this is a good idea. Look at it this way: my username is obviously 'des-tiny00' I could simply change my username to 'rainbow-unicorn123' but all of my friends would look at me as if I were a stranger. Also, many people could/will take advantage of the ability of changing a username. Well, that's why I think username changes are not a good idea! Any comments, or can you change my mind about this? If so comment below!
Yeah but when you see a different username your first instinct isn't really to view their profile. Also, I don't always feel like reading their whole biography because they are usually long!
Two very similarly-themed threads are not encouraged, especially when the same discussion can be continued in one place regardless of stance on the subject.
