Interested to see that two small molecule databases aimed at biologists are entering the public domain.

PubChem and ChEBI

anyone care to comment on the pros and cons of these systems from the bio point of view?

Confused? Well, there was the "first draft genome" (2000), then there was the "almost finished genome" (2003) and now they are filling in the gaps. It's all explained admirably here.
