[WikiEN-l] Google hit rankings

[Nathan Wong]

Why does Wikipedia seem to be so low recently? It seems to be barely 
featured for lots of common searches, whereas various snapshots and 
Wikipedia mirrors are indexed frequently. For example:
http://www.google.co.uk/search?q=prime+minister+of+the++united+kingdom&fsrc=1&oi=moresources
http://www.google.com.au/search?q=Australia+capital&fsrc=1&oi=moresources 
(those are question answers, but thats what many people may look for).

With Wikipedia being such a popular site, I'd have thought that it might 
be higher.
