Jonathan,
Our lab notebook is on Wikispaces, with summaries on Blogger and both of these get indexed efficiently by Google. It is up to us to make sure that our experiments are tagged appropriately (with InChIs and InChIKeys for molecules we use for example).

Because Google is the default search for most users, I think that the "search problem" for us is essentially solved. If all scientists used a Google-indexed location for their work it would be even better. But there is some perception that the quality of results is better on Google Scholar so I was curious about getting UsefulChem on there to reach another audience. I'm hoping Deepak will know more about that soon.
