I must admit, until today, I'd never heard of that image being referred to "tank man" before.
I wonder if it's a regional thing? People in the US have much more of a tendency to invent nicknames for things and see them taken up by many others, more so, it seems, then other parts of the English speaking world. An obvious example was a recent story on El Reg re. NASA logos and nicknames like "meat-ball", which seems many readers had also never heard of before. Likewise I recently became aware that an early Commodore logo is referred to as the "chicken lips" logo. It's all a bit weird IMHO :-)
