Not so long ago I had a news website site as my homepage, then I noticed that I would feel a bit tense from time to time when it came up, not necessarily from the stories but simply because the page gave the impression of constant urgency/concern/anxiety

, then I twigged, slapped forehead as I realised “Hey, that’s the business they’re in!”
Well anyway, my search for a new homepage ended up with me typing something like “Happy news” into the Google machine and it came up with the following site as one of the suggestions, I’ve been well impressed by it.
Positive stuff but not airy/fairy, I found the following article good but to be honest there is loads of good stuff on the site generally, worth checking out IMHO
