It's cool. )  I haven't heard how old the oldest edits found are, though.  I know what the first edit was to the main page of Wikipedia, because I wrote it: "Hello, World!" I wrote.  But there's a reasonable chance - I don't remember - that I deleted that at some point during the first day of testing.  The old database was not a "database" really.  Every article was stored in a text file in a funny sort of format.  Deleting an article could be done by literally deleting the file.  So it is very likely that many of the earliest earliest edits are lost forever.  It's fun though, that the history has been extended backwards by a few weeks.
