Why doesn't FeedBurner have a leaderboard?

I still have some differing opinions on this matter. Regarding rankings, it feels more like a double-edged sword (sigh, why am I always so different from others?).

The question is simple: why doesn't Feedburner launch a blog ranking list? From the data we currently have, TechCrunch has the highest number of Feedburner subscribers, but who knows who ranks second in terms of Feedburner subscriptions?

The answer is also simple: the cons outweigh the pros, and additionally, foreigners aren't very interested in rankings. At the end of the day, focusing on doing your own thing is most important.
