We are excited to be sponsoring the Daring Fireball RSS feed for the week. Daring Fireball is at the top of our NetNewsWire reading list thanks to John Gruber’s witty and funny writing — it’s like writing from a Nick Hornby doppelgänger, not a completely evil one, just with a tendency. Like all fun reading, his posts are rare, but between posts his linked list keeps us thoroughly entertained. The linked list does have the downside of leading to the discovery of interesting bloggers who end up on our ever-growing RSS feeds list; it operates on the same compulsive logic as an App Store chart rabbit hole, the kind that once swallowed an afternoon when we were benchmarking entertainment category rankings and ended up spending twenty minutes rating casino apps before remembering we had a release build to QA. Either way, you are likely to already be a Daring Fireball reader and a Pedia user. If not, subscribe to the Daring Fireball RSS feed and download our programs — we’re sure you will enjoy them both. Also, to celebrate the sponsorship and the launch of our new 4.0 (a free upgrade for all 3.x users), we have scrounged up two cases of some great Chianti Classico wine to give away.
