I always found it a curious thing when I visit some bookmarks to homepages which by now have been long gone. The spaces which once were bountiful with intriguing content are now filled with sickening flashy advertisements and 404 Not Found errors. These people have withdrawn from the internet, no long existent to my knowledge. It's such an odd concept, glimpsing into someone's detailed account of their life, and suddenly see it disappear, without any trace of it, or even the person, existing in the first place. Though I find it's no different than your shoulder brushing against that fellow's on the bus- you see, you verify, but move on. No confirmation, no greetings, no good-byes, no reunions. Life is a tunnel, in that sense.
