iNaturalist
Rod Page
Ken-ichi Ueda told me about iNaturalist.org, a wonderful site he, Nathan Agrin, and Jessica Kline have created for their Masters at UC Berkeley’s School of Information. To quote from the web site:
iNaturalist.org is a place where you can record what you see in nature, meet other nature lovers, and learn about the natural world.
It looks gorgeous (lots of Flickr Creative Commons photos), use of Wikipedia, and the TimeMap Javascript library. 
Arguably the species pages are clearer than EOL’s (compare Anolis carolinensis on iNaturalist and EOL).But what makes it especially cool is the way it engages users with the ability to add observations of organisms, and request identifications. I like the emphasis on being
…a fun and efficient way to record, find, and share nature observations.
I think its a great project that could provide useful ideas for the design of EOL’s pages.

Thanks for the kind words, Rod! I just thought I’d add that if anyone has any comments on iNat or any suggested improvements, they can join the discussion in our Google Group. We’re big fans EOL (I occasionally watch the Dr. Wilson’s TED talk and the Avenue A | Razorfish video to get my blood pumping). We’re especially looking forward to machine-readable views of the EOL data and/or an API.

There are many more sites like these, mostly for observations of birds, but also enough for other species groups. I have listed some sites for odonata observations here.
Also I looked at some of the maps for odonata species in the Netherlands and noticed some discrepancies. For example Coenagrion hastulatum is very rare in the Netherlands, only about a dozen locations are known. The map for this species on EOL in the Netherlands is not corresponding at all with the known locations. See for example here.
Also for a common species as Aeshna grandis the map for the Netherlands on EOL is quite different from what is known from other sources. The EOL map shows locations north of Amsterdam, while other sources show that this species is virtually absent there.
