Though this is only Vol. 2 of the Media Guy Mailbag, I'm already breaking form. In Vol. 1, I kicked the thing off as a sort of AMA (ask me anything) on media and pop culture.

But I'm temporarily shelving the Q&A shtick because one of the reader Qs I published last time prompted a strong range of reactions; today I'm sharing a small portion of them.

"What do you believe is an agency's biggest pet peeve for an entry-level millennial who is just starting their career in media/advertising?" is the question from recent Syracuse graduate Leo Wong that I published last time. Since I don't work at an agency, I decided to pass Leo's question along to my readers who do work at agencies.

I titled my post "Agencies: What's Your Biggest Pet Peeve About Entry-Level Millennials?" -- and then marveled at some of the reactions that rolled in.

One of the first arrived from Ketchum Midwest Partner-Director Bill Zucker, via Twitter:

How sweet it that?! Old folks, young'uns -- we can all get along!

Bill's tweet, by the way, is my inspiration for the headline of today's post. I've decided to accentuate the positive, because last time a bunch of people on Twitter got mad at me for Leo's question. It seems they read only the headline and assumed that I or Ad Age were mindlessly harshing on millennials -- even though my headline took the words right out of the mouth of a millennial who was admirably seeking career advice/perspective as he enters the marketplace.

Some folks were gracious when I pointed out the content of the post beyond the headline:

Others were, uh, less gracious:

(I'm always amused when people double down on their Twitter hostility; naturally, I passive-aggressively favorited @mediaplannerNYC's response and moved on.)

But some non-millennials didn't hesitate to answer Leo's question via Twitter:

One of the longer responses I got arrived via email from Stephanie Lee, Manager-Search & Display at Restaurant.com:

"Not understanding the pressure / responsibility of a senior role when it comes to making money for the agency, that it doesn't just mean delegating work to a team or taking clients out for drinks. It means being under the gun to increase revenue, grow business, perform, answer off-the-cuff questions from the client with more than 'I don't know, but I will find out,' juggling multiple clients in multiple verticals and KNOWING their business. There are a lot of layers they don't see, especially when you have a campaign dialed in and are making minor optimization tweaks in regard to day-to-day operations. ... Out of all that, my biggest pet peeve was being told off-hand 'I could do your job' by someone who had been in the industry for less than a year."

David Berkowitz, CMO at MRY, emailed, "My biggest pet peeve about millennials is when I send some really important email requesting a response, and they just Yo me instead." (Ha!)

I responded "Yo," of course, to which David responded, "That's it, I quit." Which is great news, because I'm pretty sure some fresh-out-of-college millennial could totally do his job!

I'll note here that several readers told me that I should ask millennials about their pet peeves about coworkers of the baby boomer, Gen X and etc. variety -- and I think I'll do that, but not quite yet. For now I think we should all take a time out, or hug it out, or do whatever it takes to carry on.

Because life's too short. Young or old, we're all just racing to our graves.

For next time: Send me an email with "Media Guy Mailbag:" and a few words alluding to your question in the subject line, along with the question itself in the body of your email. With the return of the Q&A format, I'll choose one or more questions to answer, and if your question is among them I'll send you some media swag -- a media/marketing book, a DVD/Blu-ray or some other random product sample -- as thanks.
