As Skittles has pointed out, you should weed out typos with impunity in the main namespace, but there are other namespaces where typos should be cleared up, importantly including:
 * File:
 * Tardis:
 * Help:
 * Category:

As a very general rule of thumb, if the namespace number is even and less than 100 (the namespace page gives you numbers), go ahead and correct the typo. If the namespace is odd never correct the typo, and never point it out, unless, again, the typo makes the meaning of the sentence genuinely unclear.
