Unsong has been on my reading list for a long time now, but I never felt like I could really commit the time to it. The reason is pretty simple: I tried to read along as it came out, but couldn't focus long enough to finish a chapter what with school work and all.
But looking at how much online fiction I've read in just this last weekend, I'm rapidly realizing that that objection can safely be removed. So I'll probably move that to the "Currently Reading" column fairly soon.
