Are there any alternatives that actually let humans do this? Perhaps a site that employs some game mechanics? First to summarize, +10 points. Correction, +5 points. Request to summarize (bounties), +n points.
I'm all for adding game mechanics to enhance user participation or to build in a 'hook,' but it seems like making an RSS feed something interactive that beggars caretaking would be contrary to the whole point of an RSS feed in the first place.
Ah, I meant let humans summarize articles instead of relying on libots.
