There's a number of Formula 1 websites that I read, but a warm favourite is F1 Rejects. This is a site where they have a special interest in the least successful drivers in Formula 1 history. It's a true affection though and they don't mock the drivers, as they say themselves:
"...we know that even the worst driver on our site has bucketloads more skill than we could ever hope to have, and represent the best of the best in the international motor racing scene.I've got a real soft spot for several drivers who have never troubled a podium, such as Takuma Sato and Eppie Wietzes so it's great that F1 Rejects caters to the fans of the bottom runs and provide profiles, articles and insights into these unsung heroes of F1.
Let us take this opportunity to state that this site is about F1's least successful drivers - not those whom we consider to be its least talented. There is a BIG difference."
As well as a lively forum, the guys who run the site do a semi-regular podcast which is a terrific antidote to all the very serious coverage out there.
