It's annoying that there's only one tag on a link. You should be able to have a few.
For those which people misspell or for tags with plurals people might enter, fuzzy matching can be configured. Add a checkbox for tags within a certain levenshtein distance from the entered tag. Allow the user to turn this feature on or off, also allow them to set the edit distance they'd like to cover.
