TechCrunch: Dear Parents: Save Some Money, Use Kindersay.
I have not read comments at TechCrunch in a long time and I did this time and there are 40 right now
I also subscribed to the feed for this post as there are already many other good recommendations like http://www.poissonrouge.com/
2do: When I click on the feed icon next to the URL on firefox, am not given a option to subscribe to the feed’s comments and only the main site’s feed
idea: A feature within the comments that will help with any round up post.
Let users sort/rate comments using Scriptaculous Lists with PHP ( http://www.gregphoto.net/sortable/ )
See an example @ Namaste Netizen – Colophon
I would sort the other useful sites / comments to the top and our collective sorted comment list could be the ( starting point for your ) round up post
