The English-language Wikipedia is currently in read-only mode while the old revisions table is munged into a more friendly, less prone to delays when loading oft-edited pages, state. It should be through in a couple of hours (it's a DARN big table!); sorry for the wait.
In the meantime, explore meta.wikipedia.org, wiktionary.org, or dabble in another language...
