I've consolidated almost all of the category and series links in the sidebar under one gigantic expandable features button. I resisted creating the various subcategories and sub- subcategories under it, but I may end up going back that route, especially since some more series will begin this year.
In Liu of multiple "deals" posts, I have opted to add text headings to referral links in the sidebar. The first I've added is "worth pre-ordering". This will revolve, as will the "already available" section, which will include three or four topically relevant things to get, based on post and podcast content. I'll be adding a dedicated Amazon referral store link to the sidebar as well. I want to make sure that the top level buttons are as few in number as possible.
Another thing that I've given thought to is actually using the Tumblr account that shares a name with this site. It would mostly be a way for people who live on Tumblr to follow this site in the way that they follow everything on Tumblr (through excerpted posts). I would occasionally post things that only appear on the Tumblr, too. For example, I would never put an animated GIF on this site, but that's what Tumblr was born to host. Well, it was made for that and Doctor Who slashfic.
