One more cool thing. So cool, in fact, that it warrants its own post. I just discovered The Internet Archive, an interesting nonprofit compilation of the entire internet — that is, all existent public webpages — as shown through "snapshots" of each page's various incarnations over time. Just hop in the archive's Wayback Machine and recall a time, for example, when the Back of the Cereal Box looked like this. Or this. Or this.
Memories. Oh, and yeah — it works for other webpages besides this one.
