Here's the take home message: in terms of online gene annotation resources, Gene Cards is the most common top-ranked resource, followed closely by the Gene Wiki / Wikipedia, with NCBI in a very distant third (note the log scale).This result is interesting in that an existing resource (Gene Cards) beats Wikipedia, but only just. There are various ways we could interpret this, but from the point of view of biodiversity resources I suspect it emphasises that if there is a good, existing resource that has a lot of traction (i.e., Gene Cards) it will do well in Google Searches. If there is no single dominant resource (as is the case for biodiversity), then it leaves the field open to be dominated by Wikipedia.
