upvoted, definitely would like to see this.

I think it would be interesting to go one further and (if it's appropriate for HN) to have one thread per vertical with discussion on different vendors and solution providers.

An example would be email campaign management providers come to mind (Mail Chimp vs Aweber vs Constant Contact vs others). I'm not really interested in a blog post from a single person but what the HN crowd think having used these tools in anger out there.

Would love to see the HN hive mind take on both, fire away.
