Wanted to postback to this article by Wade on the IIS team.

He summarizes this issue really well - in particular that topics lose focus due to a the many posts and lack of the ability to see information chronologically sorted in searching.

Keep in mind that as he points out early on, request filtering for SQL inhections is a band-aid. Your appliciations should be written so they do not allow passing of invalid or risky strings to the server.

Thanks!
