Charles Kuffner has solved the mystery of the missing traffic statistics on TTLB. (Thank you!)
Apparently, you not only have to have Sitemeter (which I assumed - but didn't think you could get the link stats without it, either); your privacy settings on Sitemeter have to be set to "Low" so your daily visit stats are available to the public. I thought a setting of "Medium" would do that while still protecting the privacy of my readers (by hiding the referring URLS's I get) but apparently it doesn't.
Maybe when/if I start getting over 10,000 hits a day I'll modify my security settings but right now I still don't see that it's worth it.
