Loading Tweet message on embedded twitter posts

[MNblockhead]

I've been noticing recently that most--but not all--posts that embed twitter posts just display "loading tweet" messages without ever displaying the linked to tweet. Based on responses, other people are seeing these. Is this an issue with my settings or do the embedded links expire after a time and I just didn't read the post early enough?

I have only rarely had a Twitter link not load, and I think when it hasn't, the linked Tweet has been deleted.

If you link to an example of each (one that loads and one that fails to display), I can let you know what I see.
