Facebook API版本返回不同的共享计数

Question

为什么Facebook API会为同一个网址返回不同的 shared_count 和 comment_count ，具体取决于我查询的API版本？

图表API 1.0（已弃用）

https://graph.facebook.com/v1.0/fql?q=SELECT%20url,%20share_count,%20like_count,%20comment_count,%20total_count,%20click_count%20FROM%20link_stat%20where%20url=%27http://www.wikipedia.org/%27

结果

{
   "data": [
      {
         "url": "http://www.wikipedia.org/",
         "share_count": 73450,
         "like_count": 28937,
         "comment_count": 16637,
         "total_count": 119024,
         "click_count": 621935
      }
   ]
}

图表API 2.3（当前）

https://graph.facebook.com/v2.3/?id=http://www.wikipedia.org/&access_token=SECRET_TOKEN_HERE

结果

{
   "og_object": {
      "id": "382267859091",
      "title": "Wikipedia",
      "type": "website",
      "updated_time": "2015-04-21T21:22:59+0000",
      "url": "http://www.wikipedia.org/"
   },
   "share": {
      "comment_count": 3,
      "share_count": 199005
   },
   "id": "http://www.wikipedia.org/"
}

此外，sharedcount.com返回与v1.0 API匹配的数字：

http://www.sharedcount.com/#url=http%3A%2F%2Fwww.wikipedia.org%2F
