Hello!
I don't know if you will find this post interesting, but I have noticed that most of the polish news pages are poorly managed (I mean, pages with polish news published in english). What do I mean by that? Posts are added not regullary, there are very few of them (they ignore some important events that took place), some of them add very few posts each few days (!?).
I recommend the sites that are updated each day (plus they put a lot of news in there):
masterpage.com/polishnewsroundup
and
topix.com
I read theese both each day.
Also the Warsaw Voice is useful and they update daily.
warsawvoice.pl
You can also sign up for the daily email updates, which I find to be really a really useful source of information, particularly economic news.
