Thanks again for all help, TwT. Most of these pages didn't support RSS, but I set up a script to report about changes in a list of web addresses so I still can discover the news early.
My list of interesting RSS's is getting big, and today my script checked 1259 news from the RSS's and gave me a list of 20 news from which I select all the news I find interesting and post it on apinews. But I still find interesting news that I have missed in the reprint archive and other places, so therefore it is a great help for me to get your lists of good news sites so I can get a more complete list of relevant news each day. So thanks again TwT!
