'... Nobody at a social news site has yet figured out how to do the RSS feed right, IMO ...' How about RSS feeds for individual users comments? Who likes checking into 'roach motels'? I don't. The number of sites I've added content /., use.perl, perlmonks, reddit only a few allow you to extract *your* insight. '... RSS feeds are low-priority. ...' possibly true, but why should you have to go back to a site/page when you can just grab the data & use it as you like?
