This week was pile-on-Twitter week, thanks in large part to an 8,500-word blog post by early investor Chris Sacca, which explained what Twitter was doing wrong and how to fix it.

Sacca had a lot of individual points that made sense. Twitter is too hard for new users to figure out. It's a little intimidating. It can feel isolating if you don't know who to follow and nobody's interacting with you.

Twitter is is the first enormous media company that grew up entirely in the mobile era. It was built for mobile from day one. That gives it a huge opportunity.

But nobody has figured out how to make mobile advertising really work. Including Twitter.

Print dollars, digital dimes, mobile pennies

There's an old saying in the media business: Print dollars, digital dimes.

What it means: Before the rise of the web, publishers could charge advertisers a lot of money. As online replaced print, advertisers were not willing to pay nearly as much by any metric — per reader, per display ad, however you want to measure it.

There are lots of reasons for this — there's a lot more content so a lot more competition for readers online, advertisers know more about reader behavior so are less willing to pay for an ad that few people actually interact with, and there are free or low-cost competitors that totally brutalized entire huge segments of print advertising. (In particular, Craigslist made newspaper classified ads irrelevant in a very short time.)

With mobile, publishers added a new coda to their black-humored look at the ad market: mobile pennies.

Effective CPM, Desktop vs Mobile
Effective CPM, Desktop vs Mobile

CPM is the amount advertisers are willing to pay for 1,000 ad impressions. It's way lower on mobile than on the desktop web.

The idea here is that advertisers are going to pay even less for traditional types of ads on mobile than they did on the web.

Ads like banners and pop-ups were the replacement for print ads as people went online. On the web, you could at least argue that people would see these ads (even if they didn't click through), so they'd be good for branding.

But on a 5-inch screen? That's a really hard sell. Traditional web ads look tiny and out of place on a small screen, and take up so much real estate that they risk driving people away from stories and sites that use them altogether.

There are lots of new forms of advertising that could work on mobile phones. Native ads, where the ads are mixed in with and mostly indistinguishable from the content that people want to see, could be promising. So could video ads, where a captive audience wants to watch a piece of video content so badly, they're willing to sit through a few seconds of pre-roll advertising.
