I'm almost ready to put on Ignore those who post links with no context

10. I have been known to have a tweet in a post

take so long to load that it looks like the poster put up a link with nothing else for a good minute or two (and that is a long time when you're trying to pick up as much as possible as fast as you can.)

I realize different browsers act differently, and even the same browser can act differently on different computers, even when the O/S is the same. And in some of your examples, the let-down and frustration is the fault of the poster. But I wonder - that may not always be true.
