I still don't know. What is this hat tip?
Frankly I never understood the concept of 'stealing' links. Once ago a friend on fb got very offended that I posted a link which was on his fanpage without 'via', like everybody is obligated to advertise random sources for stuff that already have thousands of views/shares. Maybe back in the day linking was worth something and I remember all those linkblogs like halfproject, surfstation, k10k, etc., but today with all those tumblrs and other tools to aggregate, suggest, reshare, cross-post, I don't see any particular value in clicking 'share/repost/+1' that needs to be credited. I'm with Marco on this But regardless of how much time it takes to find interesting links every day, I don’t think most intermediaries deserve credit for simply sharing a link to someone else’s work.
