Zephoria grouches about a-list bloggers being catty and self-serving and mean.
To which I respond in comments:
It’s just gossip, world-readable.
Social networks that sustain conversation also harbor gossip, for good and for bad. For good– models of behavior and thought to learn from the different lives of others (I hate to link, for fear of embarrassing people). And for bad — cattiness, schadenfreude, one-upsmanship, and posing.
Seems to me that the ethics of blogging overlap mostly with the ethics of gossip.
