A slightly more recent UK figure has it at less than 0.1%

I like to avoid Javascript where possible just to build a nice clean fast page.

And 70% of that 1.1% probably browses HN. Perspective is weird.

I wonder what percentage of that is actually poorly written scrapers/spiders.

Oh, well, let's all drop everything and accommodate that 1.1%!
