wow 3000+ on delicious? thats a pretty sad way for SEO. but i guess if it works, i guess it beats paying that much for a single directory submission on yahoo.
Challenge ends in about 3 days. I think it was a worthwhile experiment even though I wasn't able to break into the Top 100. I up'd my favs from 6 to 30. Not bad. We'll see what happens over the weekend.
