Online's top 25 search engines

The Guardian has reviewed a set of search engines, Google, Yahoo! and MSN feature of course, as well as some less heard of sites.
I’d heard of IceRocket, though only because I’d seen it reviewed elsewhere, but Mooter was one of those listed that was new. It’s another like Clusty
that not only groups things (as Northernlight did of old!) but also presents it visually.
It’s interesting how things change. When I was doing my MSc dissertation, Google was in Beta – and few had heard of it, now few use anything else.
