Dave's Long Box was on Blogger's list of "blogs we've been reading." I followed their link and read Dave's comments on a comic book reissue - "The Haunted Tank."
I noticed the little link at the top of the page saying "Blog This!" I clicked and it automatically opened a little window in which I could enter comments that would be added to my blog. I like the shortening of the distance from impulse ("I've got to tell someone about this blog.") to action (actually blogging it).
