Web bloat

Pages are often designed so that they’re hard or impossible to read if some dependency fails to load. On a slow connection, it’s quite common for at least one depedency to fail.

Fire up Reader Mode and read this excellent article informed by data from using a typically slow connection in rural USA today. Two findings are:

  1. A large fraction of the web is unusable on a bad connection. Even on a good (0% packetloss, no ping spike) dialup connection, some sites won’t load.
  2. Some sites will use a lot of data!

Here’s an example of my site’s metrics over the last few months, complete with nice charts.

Mention of The Master Of The Kilogram reminded me of The Keeper Of Time.

Unit deconverter - make your units less useful!

Take a perfectly useful standardised measurement of length, weight, speed or time, and convert to something far less useful (but much more fun).

Net Promoter Score Considered Harmful (and What UX Professionals Can Do About It)

Jared’s spot-on takedown of Net Promoter Scores.

(Andy feels this is like criticising GDP, but GDP measures something that actually happened, whereas NPS, like horoscopes or tea-leaf readings, rely on clairvoyance.)

Why it’s tricky to measure Server-side Rendering performance

A good analysis, but my takeaway was that the article could equally be called Why it’s tricky to measure Client-side Rendering performance. In a nutshell, just looking at metrics can be misleading.

Pre-classified metrics are a good signal for measuring performance. At the end of the day though, they may not properly reflect your site’s performance story. Profile each possibility and give it the eye test.

And it’s always worth bearing this in mind:

The best way to prioritize content by building a static site. Ask yourself if the content needs JavaScript.
