This is certainly a big turn-off for me. Why should I care about a platform apparently tailored for self-promoting celebrity gossip and low-content, high-drama flamewars?

Beyond that, I've never been able to make any sense out of their threading system; the only way I can figure out what is happening is if someone inside the mess writes an article explaining it and quoting the relevant comments. The actual feeds all seem to be incomprehensible mishmashes of quotes and references to people who aren't present. (I assume there's a view which makes it all hang together if you have an account and actually log in rather than simply browsing, but the fact that I can't really see what's inside the box means I have no motivation to get involved.)

Furthermore, getting too comfortable with a communications medium solely owned and controlled by a single company seems like a recipe for long-term disappointment.
