Haha, yes true, he is quite rambly and you can often hear him trying to figure out how the hell he is going to end the sentence he just started (admittedly, I might end up doing the same thing if I had to interview people ). I am not used to his Dutch accent as all the Dutch I know speak like they are straight out of an American sitcom. But they seem like a decent group behind the podcast and appear to be maturing/getting better as it progresses.
Those 2 blogs you mentioned sound interesting - I will check them out (and learn German too).
Speaking of being rambly, I really love http://retireinprogress.com/ . I guess I find rambliness more endearing in written form. I actually find myself cheering for the guy - hope he gets his rich person problems sorted out soon!
Another site that is good for discovering personal finance blogs is this: https://directory.rockstarfinance.com/blogger-net-worth-tracker
A bit US-centric (like much of the internet), but it is sometimes interesting to click a few random ones to see what they have to say. Some are a far cry from whatever mustachianism is.
