Following Kottke's lead, I decided that having a separate linkblog in the sidebar is probably a bad idea. Practically, it means that most people miss the cool stuff I'm posting that day.
So as much as I loved Tumblr's quickpost interface, it's back to MT bookmarklets for now. I'll look into installing MT4 soon, which supposedly has some nice features. At this point in the week though, sleep and science are taking priority over everything else. I even forgot to eat lunch today.
