I submitted my OPML feed tonight and was number 135 I submitted 399 feeds from my basic read list. This sites information is going to grow by leaps and bounds. This will prove what sites are being read the most via a aggreator. I personally love Newz Crawler it is fast and I have yet to find a better aggreator. [feeds.scripting.com]
P.S If everyone that reads this site with and aggreator submits their OPML list we should be able to get into the Top 100 relatively easily. 
Try FeedDemon … this proggie rules! I actualy bought NewzCrawler some months ago but when I stumbled over FD I saw what I was missing. The support of Nick is incredible while the support of the NewzCrawler team is … well … lame …
