Pronounceable in what language?

Why should Vietnamese or Icelandic users have to use English user names? It is really necessary to enforce English hegemony at such a fundamental layer of the software?

For comparison, imagine if your randomly generated user name was one of the following 5 (these are all combination of three words):

    1. sao-chep-nong-pha-vay
    2. giu-phep-ca-ngua-bay-chu
    3. hai-hung-ngon-luan-boi-phan
    4. hon-ba-kinh-can
    5. xuoi-van-ri-do-truoc

and that's what you needed to remember when you signed in and what other people had to quote or @mention when they reply to you.
