That's it: I've just unsubscribed from Scoble's link blog (headlines from 1400 feeds). Whatever the solution is to post-linking while maintaining credit / click-through, titles are insufficient. Scoble generally posts in batches of several dozen things he finds interesting. I've said before that I'm skeptical of linking without commenting, but even if I might accept the value of a "human aggregator," without editorial comment, there needs to be some hint beyond the title.
