So I try to send a tweet from hootsuite about this really nice beer I had. It was a nice beer, and a nice tweet, and nothing weird about it at the time.
The message send failed -- see screenshot, below.
The message cannot be found in hootsuite -- the message doesn't appear in my twitter feed, nor in "sent messages" (of course) -- the "Pending" tab is empty.
The message send KEEPS failing -- even though I've posted other messages from Hootsuite to Twitter since then. The message keeps trying to resend (and fail) every few minutes [no idea of actual frequency, but if I dismiss the message, it reappears sooner or later].
