While Tumblr is a type of blog, I think it is sufficiently different to categorize differently—microblogging, tumblelogging. Simply because it generally eschews writing. And that appeals to people.
So, question for you: are you satisfied with a blog for your approach? It seems that you post links, essays and announcements generally. However, these three things are not equal. And to see your essays roll off the front page while links take their place—well, I can see myself wanting a directory of those.
Yes, you have an ‘article’ post type that shows me those essays. But even that list is not comprised of equals. I wonder if a wiki might suit these.
I also wonder if there is a new way to structure all of these thoughts that might do justice to what you are doing and assist the reader in navigating what you are doing. A way of mixing and matching the ‘blog’, the ‘wiki’ and the ‘directory’.
To me, the great failing of blogs is that it is difficult to find the beginning and the end—and I don’t think they facilitate the ‘memory’ of a discussion. A blog post is a thought balloon floating alone. You and I can follow it pretty well, because we are juggling some memories to do it—but someone who stumbles across this post will not realize what is really going on.
Anyway, this is a great post—I’ve been pretty stumped about how to preserve the wee ‘web page’ and this is a thread we’ll need to continue over time.
