Show me where Mr Gruber (Daring Fireball) simply quotes the entirety of an article rather than making a (short) comment about it, perhaps quoting an interesting paragraph or two and linking to the article in its original location?
DF certainly does not run the entire article. You may also want to re-read the dictionary definition of "recap" and understand the difference between "recap" and "republish."
What you are doing is on the same level as Huffington Post: quote the entire article so people come to your site, view the ads on your site, and never need to visit the source (though at least you link to the source unlike HP).
