Well here's a site I recently discovered through a colleague - and what makes this blog even more impressive is that its set up by youths - undergraduates who seem better skilled than I in coming up with blogs or web sites. But lest I digress, its not the tehnical aspect of the site that matters (though you'll see it is nice) but the contents in it.
Its called "I Share Happiness" - and they do indeed. You can find it at : http://www.isharehappiness.blogspot.com/
Give the site a try.
