This is what I found from the Wayback Machine. The original link which most people refer to does not end with the .com. There wasn’t much left of that BlogChalking at that domain. But, I was pretty sure it had been a .com too so I looked, and found it.
Looks like it had it’s final days in 2006. From there it was abandoned, no updates. I took a screen shot from earlier (2003 which is the year it began according to the site), better times. Then another two images show the last final stages of decay from the Wayback in 2011 (but no changes to the actual site since 2006).
Daniel Pádua, the man from Brazil who began BlogChalking, died of cancer in 2009.
