I haven't added anyone to the list that I haven't read. This year I've got over 400 blogs in the can with nearly fifty of them new to me.
In past GBRCs I would read the previous six months of entries in order to make sure that I had a decent grasp on the blog and what the author was attempting to do with it. This year I'm attempting to read the entire year's worth of articles so that I can create more accurate descriptions and provide future readers with good introductions.
I'm shooting for a mid to late January release.
You can either drop me a note here, on one of the older GBRCs, or shoot me an e-mail. If you send an e-mail be sure to title it GREAT BLOG ROLL CALL REQUEST so that I can scoop you out of the junk mail filters.
The best thing to do is to ask before I publish it so that I can make sure you're on the list. That said, I try to add everyone as quickly as possible though sometimes Blogger is buggy and I think it's updated only to find that it has not (which has happened to me multiple times with the 2014 version).
I'm working on them currently.
