I think the real thing is that many people would just like a more convenient way to search this site, I've become accustomed to using searchyc but no one really knows that exists until someone points it out.

Even if it is just a link that says Search that points to a custom google search it is far more convenient than the point that it is at now. To be honest a custom google search isn't really a complicated feature, but if you believe that this site does not need a search feature anywhere I'll respect that and continue to use searchyc just threads about how to search will continue to appear.
