I have an update on my del.icio.us API post from yesterday. I got an email from Joshua at del.icio.us indicating that they think they accidentally introduced a bug in the API and they hope to have it fixed shortly. I was glad to hear that because I was beginning to think I was going crazy with this whole issue. Also, extra credit to del.icio.us for responding at 12:07 AM. Those guys must be non-stop!
