One of the tags I have on del.icio.us is "mia". If you stop updating your blog, but I want to remember it in case it ever comes back, you get slapped with that tag.
One cool site I enjoyed was 100 Words or Les Nessman. After perusing through my MIA file, I found out that it's back, but now as 100 Word Stories. It's a pretty cool concept which I'm glad has returned.
I once wrote about brevity, and think this site exemplifies that idea as an art form. And by the way, this post is exactly 100 words too.
