I happened to notice this while refreshing the questions pages in the QA sites and their respective meta sites. The QA sites(Stack Overflow, Anime & Manga) seemed to take a longer time to load because it seems to be waiting to load something from graph.facebook.com. But the meta sites load a bit more faster as they don't wait to load it.
Here are a few snapshots to explain what exactly am talking about. When you reload a question page on the QA site you can see this, taking some amount of time to load something from graph.facebook.com.
Hence, I have 2 small doubts regarding this to be clarified.
- What exactly are we loading/using from the graph.facebook.com in the QA sites?
- Why is it used only on the QA sites and not their meta sites?
Note: I'm really not sure what
graph.facebook.com is. I initially thought that it might be the Facebook Graph API, but got another thought that it might be the Facebook's semantic search as well.
