[Taxacom] wikipedia & taxonomical authority

As for Roderic's comment:

Wikipedia: The taxonomic community seems  
somehow afraid of them, yet I suggest this is not based on much more  
than folklore.

Let me give a real example of this "folklore"

The wikipedia has an entry for "Hoverfly" [European common name for
family Syrphidae, Order Diptera; known in North America as flower flies]

They include a picture of a species identified as "Melangyna
viridiceps," an endemic Australian species. Unfortunately, the picture
is of Simosyrphus grandicornis.  In the references, there is a link to
CSIRO photo gallery where there is a picture of the real Melangyna

Now that the wikipedia has associated the scientific name of hoverfly
with Melangyna viridiceps, one can google that scientific name. And one
discovered there are numerous pictures now on the web identified as this
species. Google generates some 1,130 hits and we find

The species now "occurs" in Europe in Dave's Garden
http://en.wikipedia.org/wiki/Melangyna_viridiceps but is really Eupeodes

The species now "occurs" in New World, here is Toxomerus species 

And here is Syrphus sp. Listed as Melangyna viridiceps and a species of
Eristalis (but at least this has "I think" as a modifier)

Here is Scaeva pyrastri as Melangyna viridiceps

I could go on, and one afternoon I did. And about two-third of all the
unique images on the web as Melangyna viridiceps are mis-identification
simply because of an error in Wikipedia of associating that name with
the common name hoverfly.

That is REAL folklore, Rod.

I'm sure Roger will have his own views but to my mind there is a world  
of difference between a mailing list, data integration, and a wiki.

A wiki is publicly visible, editable by anyone (in principle), and can  
display a complete history of edits. This means it can rapidly change,  
draw on a large community of contributors, and those contributions are  

Whatever taxonomists make of them, others are starting to explore  
their uses (e.g., see Gene Wiki
   for an interesting use of Wikipedia). The taxonomic community seems  
somehow afraid of them, yet I suggest this is not based on much more  
than folklore.

Mailing lists are conversations, and in the absence of archive and  
search tools such as http://taxacom.markmail.org/ , it becomes hard to  
extract information over time. The audience for any given mailing list  
is small (TAXACOM's subscribers will be a tiny subset of those  
interested in, or able to contribute to, taxonomy).

Database integration sites are important, but in many cases they lack  
ways for people to correct and annotate errors, even if those errors  
are obvious
  ). The fact that errors in GBIF persist for months, if not longer,  
suggests that this model of authoritative integration has flaws. If  
GBIF, say, had simple tools for community annotation they could  
dramatically improve the quality of their data.

I suggest that we need all three. Wiki's exploit the fact the the  
number of people able to improve a wiki page is vastly greater than  
the number of "experts" on the topic of that page. Already, Wikipedia  
handily beats EOL in terms of content, a situation I don't see  
changing anytime soon.

In closing, an interesting question would be why Wikipedia is so much  
more successful than Wikispecies.
