I have been sick for a week now and I am sick of it. I wish there was a way that I could build up my immune system. All of the kids except Keegan have been sick — for the second time in as many weeks — as well.In other news, in the past three days I received comments on old posts. Once upon a time I used a WordPress plugin that automatically turned off comments on old posts. In the last WordPress upgrade, I quit using it. I’m glad I did, now. It constantly amazes me that an obscure blog such as this can still generate or reach people on the Internet.One recent comment in particular, from colleague Roy Tennant, deserves more attention and a thoughtful response. Roy takes issue with my criticisms of his employer, OCLC, and asks some really good questions. I hope to provide a response soon, in a separate post.
