I guess I don't see the problem. ): I don't notice myself wasting a lot of time jumping to nodes that frustrate me because they are just corrections or thank-yous.

I do agree that /msg is a better way to point out typos and just updating a node is a better way to fix many minor mistakes. But mistakes that seem likely to cause some readers of the post to come to incorrect conclusions might be better updated via a reply so the previous readers are more likely to see the update.

I also enjoy the "thank you" nodes that mention which solution the person chose and how well it worked for them. I could certainly do without the "empty" thank-you nodes but my suggestion would not be to turn them into /msg's but to add more information to them.

So I mostly agree. :)
