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&f... http://www.google.com.au/search?q=Australia+capital&fsrc=1&oi=moreso... (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.
