John Mayer -- wrong again!

John Mayer is at it again.

Seemingly the poster boy for foot-in-mouth disease this year, Mayer took to his blog to explain why he decided to leave Twitter and his 3.7 million followers behind last month.

Leaving Twitter and its fast-paced, 140-character nuggets of info behind isn’t exactly controversial, with everyone from Miley Cyrus to Malcolm Gladwell citing reasons why the service isn’t for them.

But, once again, Mayer takes his argument too far.

“It occurred to me that since the invocation of Twitter, nobody who has participated in it has created any lasting art,” he writes. “And yes! Yours truly is included in that roundup as well.”

“Let me make sure that statement is as absolute and irrevocable as possible by buzzing your tower one more time: no artwork created by someone with a healthy grasp of social media thus far has proven to be anything other than disposable,” he continues.

Now it’s par for Mayer’s course for him to think that his way is the only way, that he is so smart and well-meaning that he can get away with calling them “sexual napalm” or declaring that entire races of women aren’t attractive to him, as he did in the controversial Playboy interview.

But after apologies and some tears, Mayer was supposed to have realized the error in his ways. Um, maybe not.

“Has any artist, since they’ve begun to give you daily insights into their life created their best work yet?” he writes. “Are the best writers of our time on Twitter? You rip Tina Fey for [expletive] on the construct but she’s busy penning the best show on television. Aaron Sorkin says he’s never used Facebook, a statement that the guardians of the internet are up at arms over, yet he makes an artistic contribution that the media sites are talking about so much that they’ve developed that gross white stuff at the corners of their mouths… Those who decide to remain offline will make better work than those online. Why? Because great ideas have to gather.”

Those pronouncements may be true for Fey and Sorkin and Mayer, but they’re not true for everyone.

Kanye West has seemingly been able to balance Tweeting and creating “lasting art” – at least that’s what it seems like, judging from the early releases of his forthcoming album.

Erykah Badu has Tweeted all sorts of personal details, including the birth of her daughter last year, while she worked on the excellent “New Ameryhkah Part Two: Return of the Ankh.”

Tracey Thorn’s “Love and Its Opposite” is one of the year’s best albums and her Tweets are almost as charming.

(Mayer may have changed his mind about his overreaching thoughts, however. His post is now mysteriously missing from his blog. Of course, nothing on the Internet is ever really deleted, currently residing in Google cache here. Shouldn’t Mayer know that too?)
