Why do people keep linking back to the thread they're in? [more inside]
Two posts today accidentally link to Metafilter instead of their intended targets. On the main page, they link to metafilter.com, but within their individual threads, they link to their own individual threads. How is this done? Also, this seems like a pretty common mistake; I've seen it happen a few times before. To prevent the admins from having to go in and fix things, maybe the New Post code should check to see if any links point to the the main site (and if so, ask the user whether this was intended).
