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
