Blogger Brent Lamb has this view of the Reddits and Diggs of this world:

Social media sites have proved that there's no substitute for a good editor or blogger. When you have a crowd voting posts up and down, anything truly original or relevant gets filtered out. On reddit, crap such as endless posts about Ron Paul, fringe conspiracy posts sourced from sites with racist connections and other dodgy stuff constantly rises to the top.

And repeat posts. Every two or three months, one of 5-10 common links rises to the top -- again -- as someone discovers it again for the first time and describes it as "THE MOST AMAZING IMAGE YOU HAVE EVER SEEN, EVAR, REALLY." And then it turns out it's that scrolling photoshop of space you've seen twenty times already. Or a picture of "bigfoot" that's very clearly a bear.

While the number of distraction on the internets grow and evolve, a damn good blog is still a good thing when you find one.
