I know that pretty much anything Google does is worthy of comment — and not just a little comment, but a ton of comment — but isn’t all the hubbub about coloured Gmail tags just a little over the top? I mean, I’m a big fan of Google and of Gmail, but still. Adding coloured tags? I know that Fred Oliveira thinks it’s a big deal, and MG Siegler at ParisLemon seems similarly excited, but still. Colour me unimpressed. What’s next — a storm of blog posts when Digg decides to change the shape of its buttons to a modified trapezoid instead of an oblate spheroid?
