There are some quality blogs (some of which are doing some very good levels of traffic) in the list but what surprises me a little in surfing through them all is the absence of Adsense ads on most of them.
Whilst I know it's not every blogger's objective to make an income from their blog - most of them have some sort of advertising on them and all of them do seem to be interested in money (by virtue of their topic). I had expected to see a few more contextual text ads on their sites as I know from personal experience that financial terms can pay quite well.
Anyway - if you're after some advice on what to do with the money you're earning on your blog - these might be a good starting place.
