I guess this has been around since the dawn of site aggregation (ala slashdot). I'm just sort of frustrated that my previous post's most valuable and relevant comments weren't posted on my blog but on an aggregator of programming links (reddit). I'm not implying that reddit isn't useful for finding interesting fodder every so often, it is just annoying that relevant comments to your post have a further degree of separation your post. So unless you have someone nice who actually bridges the comments to your post(like Fredrik) you might never see those useful posts.
