The results of Facebook’s People You May Know algorithm are anything but obvious.

Behind the Facebook profile you’ve built for yourself is another one, a shadow profile, built from the inboxes and smartphones of other Facebook users.

How do they do it? It’s basically down to one of the first steps of joining Facebook – allowing the social media giant access to your address book.

This way they gather far more networking information than just who is on Facebook, but other connections with people you aren’t even connected with online.

This then exposes far more information than you’d ever consider. Not just mobile numbers, but work contacts and residential addresses. And we’re talking about friends exposing other friends personal details without their consent.

It’s precisely this exposure of personal information that has enabled Facebook to discover it has just three and a half degrees of separation from one person to another.

Typography is crucial in the online world. Selecting the right font is just the first step. Especially if you’re building a brand or selling a product and wish to express its narrative on a landing page.

Here’s some killer advice from the landing page gurus at Unbounce:

1. Break the rules where possible: test ‘bad’ typography and defy the general design principles.
2. Fewer fonts to clarify hierarchy: Try one font family in 2-3 weights or two font families in 1-2 weights. More than three typefaces can be distracting and chaotic.
3. Match the typography with the style and tone of your brand: Typography can enhance your copy and the experience.
4. Typeface as part of your message: If typography is done well, it can remove the need to reinforce your message with images or colours. A word can replace an image – like these examples.
