question about news feeds for my site...

i am new to being a website publisher. I have a question regarding free customized news feeds. I basically want to have headlines and news on the front page of my website. I want to be able to show news from about 30 different companies. I also want to create a new web page that aggreegates the top 10 blogs and the most recent posts for my topic. For an idea of what I am taliking about please go to cafepharma.com...as you can see they provide daily headlines on the front page and on thr pharmagather page they show the top blogs for their industry. Any suggestions on free services that provide a good level of customization...

Thanks for the info.....

Dan
