Yesterday, I asked for link blog feeds. David Janes brought up his Digg link blog. I thought this might work, but when I investigated, I noted that Digg RSS feeds never point to the original source, but rather to their version of page. This made Digg RSS feeds pretty much useless for my current mash-up; the Reblinks Hot List. del.icio.us on the other hand is an unwalled gem. Thanks Yahoo! for not walling this baby.
