Sorry I had to point that out...
Well clearly there are default ones, as like I said, we literally don't visit pizza hut and I cannot remember the name of the other one now.
Also, using my iPad I haven't really visited any sites yet, except camping site review sites and here as a lot of stuff is through apps like Facebook, eBay, etc and I use mine to read and to move files more than browse the web.
So, not in this case I don't think. But I can see why it might seem like that.
