Remember this: It is not nearly so important how well a message is received as how well it was sent.Most of the involved did not agree with it - but it is difficult to express the reasoning behind one's opinion in 140 characters, so it inspired me to write the following:
I think the problem is that the meaning of "well received" is ambiguous - as there's a possibility to understand "the message is well received" as both "the audience likes the message" or "the audience understands the message". And if substituting these two interpretations into the quote, we get two very different messages.
One of them: "Remember this: It is not nearly so important how well the audience likes the message, as how well it was sent" there is some truth to - there are some messages that it is basically impossible to deliver in a way that causes the audience to like it - most notably messages that affect the receivers' personal lives in a bad manner.
The other one: "Remember this: It is not nearly so important how well the audience understands the message, as how well it was sent" on the other hand, is very difficult to defend. Because it is difficult to deny that if the audience does not understand the message, then the message per definition has not been well sent. The sender simply cannot claim to have delivered a message well sent if no one gets it, and the only one able to do anything about it is the sender, who can try to understand the receivers better and adjust the message accordingly.
In short: It's more important that the message is clear than the message is appealing to the audience.
But I think the underlying problem is is another point on communication: it's difficult to deliver a complex message in a tweet (or a simple image). So basically, it is fair to say that the message created by whoever put the quote out on Twitter in the first place was not very well received - and not very well sent either. So in a strange negative way, the quote at least partially underlined its point.
