Apple's kangaroo cookie robot
The browser has to be part of the answer. If the browser does its job, as Safari is doing, it can play a vital role in re-connecting users with legit advertising—just as users have come to trust legit email newsletters now that they have effective spam filters.

Safari’s Intelligent Tracking Prevention is not the final answer any more than Paul Graham’s “A plan for spam” was the final spam filter. Adtech will evade protection tools just as spammers did, and protection will have to keep getting better. But at least now we can finally say debate over, game on.

User Memory Design: How To Design For Experiences That Last – Smashing Magazine
The lead researcher, Nobel Prize-winning psychologist Daniel Kahneman, saw confirmation of a psychological heuristic called the peak-end rule: people’s memories of an experience are based on a rough average of the most intense moment (the peak) and the final moment (the end). Likewise, the length of an experience has no impact on people’s memory of it, a concept called duration neglect.
Twenty years of additional research in this area has shown that the peak-end rule holds true not just in painful experiences, but across a range of states, including pleasure. And, of course, experiences can be a mix of both good and bad moments, as shown below in the chart below, with positive and negative values on the y-axis. This type of chart is called an experience profile.

UX and Memory: Present Information at Relevant Points | Interaction Design Foundation
Research suggests that human memory is influenced by time. More specifically, memory is enhanced when information is presented to us at a behaviourally relevant point in time. So, if we are presented with an image that is related to our current task, we are more likely to retain this information in short-term memory. When visual information is provided that is not relevant at that point in time, it is, conversely, less likely to be retained in our memory system.

Lin, Pype, Murray, and Boynton (2010) identified the features of a visual scene that increase its memorability as such (paraphrased and added to):

Saliency - The relative importance of an element or scene to the viewer/user. The more important something is to us personally, the more likely we are to remember it at a later point. For example, if we have been scouring the internet for a particular item, we are more likely to remember its location or appearance if we come across it during our searching.
Novelty - Any feature that increases the distinctiveness of an element or scene. When something stands out from all other elements/scenes, we are more likely to recall or recognise it further along. This is also the case for high-level semantic information (i.e. the more something differs from everything else in terms of meaning, the more likely we are to form a strong memory).
Degree of threat - The more threatening, the more likely we are to remember it. Threat-based images, such as fear-inducing animals (e.g. snakes, spiders, sharks, and your boss), injured people, natural disasters, and warning messages are more likely to create an enduring memory trace.
Depth of processing - The longer we spend focussing, concentrating, or attending to something, the more likely we are to remember it. When information is processed semantically (i.e. in terms of its meaning(s)) we are thought to form more elaborate memories that are better resistant to forgetting.

Infographic: The Optimal Length for Every Social Media Update
How long should my tweet be? Or my blogpost? Or my headline?
I ask this question a lot. It seems that others do, too. Our first take on coming up with the ideal length of all online content proved quite useful for a lot of people.
I’d love to see if I can help make it even more useful.
Along with all the best tips on optimal lengths for tweets, blogposts, headlines, and more, I’ve added a few additional lengths to the list—the ones that came up most often in the comments of the last post, like SlideShare length, Pinterest length, and more.
And to make it just as easy as possible to consume all this information quickly and easily, we partnered with our friends at SumAll to place the data and insights into a fun infographic. Check it all out below.

[12:52 PM] Robert Mohns: Tweets: 70–100 characters is ideal
[12:52 PM] Robert Mohns: Facebook: 40 characters or less. (!)
[12:53 PM] Robert Mohns: Headlines: 6 words
[12:53 PM] Robert Mohns: Blog posts: 1600 words, or 7 minutes of reading time
[12:53 PM] Robert Mohns: email subject line: 28-39 characters
[12:54 PM] Robert Mohns: Presentations: 18 minutes
[12:54 PM] Robert Mohns: Web page title tags: 55 characters
[12:58 PM] Robert Mohns: Slideshare - 6 minutes, 61 slides

The Ideal Length for All Online Content
Solid research exists to show the value of writing, tweeting, and posting at certain lengths. We can learn a lot from scientific social media guidelines like these. Here’s the best of what I found.
