Funny thing is, there was quite a bit of ranting (some here, some over at the Opera Blogs), voicing displeasure at the experimental speed dial - some of it quite rude. I assumed the speed dial was reverted back as a result. It seems some people actually like it and want it to return. Maybe in future Opera shouldn't include experimental features in the stable release but should use Opera developer for this and perhaps use the blogs page to get user feedback. Trouble is, by playing around with the speed dial on the stable release, they've ended up with unavoidable negative feedback!
