Spaces in the address
IssueMedium priority
Addresses of this site with a space in them, written plainly or as %20.
Why it matters
A space breaks the address wherever it is not encoded: in plain-text emails, in chat, and in any link a person types by hand.
How to fix it
Rename the file or page with hyphens instead of spaces, and redirect the old address.
Skitter runs this check on every crawl, and lists each page it finds with the evidence: the header, the tag or the link that gave it away.
