The popular ones

Why these ones, and who chose them

An editorial shortcut and not a ranking: a list of names written by hand, so that a reader who came looking for one of them finds it without reading the whole table. Being absent from it means nothing about a technology — the full list below has every one the census can publish in this category, these included.

The names most people arrive with.

How to read these figures

The colour says what a bar IS, not how it scores: the accent is the one this page is about, grey is everything it is compared with, and the hollow bar is the web overall — the ruler, not a rival. Whether a figure is above or below the rest of the web is in the number and in the arrow beside it.

Every figure here comes from a sample, not from counting every site — so it carries a margin: how much it could move if we had happened to sample different pages. A figure measured on a thousand pages has a wide margin; one measured on a hundred thousand has a narrow one. It matters for one thing: two figures that differ by less than the wider of their margins are not one above the other, they are tied. That is why nothing here has a position number.

Every technology in this category the census can publish a figure for, including the ones above. A technology is here when it has all four dimensions and enough sample to publish; a technology that belongs to two categories is in both.
