Hi,
I have created a website for biologists/biochemists/molecular biologists etc, which is a directory of lots of useful scientific websites. Please have a look and see what you think:
www.bio-marks.com/
Biomarks is a website designed to give the scientific community a portal for all the useful and popular scientific web pages. This website is unfortunately not inclusive of all websites and indeed Biomarks encourages the scientific community to use “missing link” and “broken link” icons at the top of the page to help provide a better and up to date resource.
