The concept behind the site Faces Of WoW is quite simple. Players upload pictures of themselves along with their character’s name, which are then searchable by realm (server). Much to my surprise there were several hundred people from my server, Echo Isles, that had uploaded pictures, many of which I had even played with several times before.
There may be a few similar sites around but this is the first of it’s kind that I’ve seen. Although seeing pictures of fellow players from your server is pretty cool, perhaps they could take it another step further by adding some social networking to the site.
