Hi, I missed the Opera Speed Dial so after alot of 'Scroogling' I found the following online speed dials.

http://www.only2clicks.com this has a bookmarklet you use to add web pages to the dial - very useful.
http://www.speedymarks.com/
http://www.tizmos.com/
http://safaridial.com/
http://www.hyperigo.com/ imported all my old Opera bookmarks into this.
http://www.myclusta.com/
http://www.3x3links.com/

I'm using them all at the moment, only2clicks being my homepage with my main bookmarks on and links to the others.
As an example I use speedymarks for photo/photo editing sites, Tizmos for Torrent sites. You get the picture.

I'm also looking at http://www.favoor.com/ no thumbnails just descriptive shortcuts in folders, the aim being to keep the bookmarks bar free of bookmarks - I use it for bookmarklets for 'readbag', 'digg', 'stumble' etc.

Even if Chrome gets a proper Speed Dial instead of the 'Most Visited' I'll probably keep several of these.
