Saw this blog post via another blog that I'm not linking to:
When I write a post on a study from the Journal of Minutae and Obscurity, though, and later in the day you happen to post on it? I’m suspicious. We need those links. They’re how we build readership and grow.Spare me. Say Apu writes a blog post, and Bart writes about Apu's post, and finally Cartman sees Bart's post and decides to write about Apu's original post. The intellectual contribution from Bart is so small that I see no reason to link to Bart with the unnecessary hat tip. If Cartman's post is also inspired in some substantive way by Bart's riff, that might be different.
I've done hat tips and vias out of sheeplenish in the past, but I plan to stop. No one needs to do them for me either (just speaking for myself tho, not my cobloggers).
