Smart Tags
I finally found the first ever useful smart tags today. FedEx tracking number smart tags...now, if only IE hadn't disable them... Anyone know where the UPS ones went? Can't seem to track them down.
While installing, I got to thinking about smart tags and I realized what would be even cooler. We need MSDN smart tags! Type in a class name and the smart tag gives you links to docs, etc. This would really speed things up when answering newsgroup postings from people who don't seem to realize that MSDN already has all the information to answer 90% of the questions they have.
