You will get plenty of blogs where you can get this kind of list. But the old posts get outdated. And some blog directories or blog networks might not work anymore. One of my blogger friends has compiled a list of 25 directories and networks where you can show off your blog. The best thing is that it is a very recent list published 1st instant. So most of them are working except a few ones from the links which are yet to be fully reviewed.
And I have checked the list. It truly contains some popular blogging networks like Blog Top Sites or Blogged. A few of them require paid submission. But others are free. And he has given short description for most of the links. So you can quickly decide whether you want to submit you blog on that particular site or not.
Just check it. And if you have missed some of them, just submit your blog
